Kart bug reports thread


hey, im new to srb2kart and also to the forums, sorry if this is the wrong place to post this but yesterday i told a friend to download the game and play on public servers, and when he loads up the server list, only a few servers appear for him.

Instead of the usual 3 - 4 pages of servers that i get, he only gets 1 page of servers that only show like 5 or 6 servers.

We tried turning off firewall, and even his antivirus and still a few servers come up. He also tried redownloading the game to have it be vanilla srb2kart but not even that worked.

The weirdest thing about it is that when he refreshes the list, different servers appear each time, but its still a very short amount on the list.


on my OSX Catalina late 2019 macbook air, the SRB2Kart OSX build has some problems. it fails to build, and sometimes it gets killed with "SIGILL: Illegal Instruction".

The following patch fixes both issues:

The online mode doesn't work anymore. When I use the internet server browser, it just searches for a bit and redirects the glove cursor to the top of the screen, labeled as "LP.L'A.Y.ERS".


You. Are doomed. Goodbye. *turns into demon*

that's just the master server not working, that happens more times than there are medals in srb2k.


Gimme more coffee!
SIGSEGV on boot, happens on both the standard and OpenGL versions.

Not sure if this little bit of information can help, but I updated my video card drivers today.


Insert funny hahas here

So I managed to get stuck inside a pipe somehow. (Kart 1.2)
I basically hit the pipe after going off the ramp, and managed to get 100% stuck inside it. A friend tried hitting me with a jet-jaws to try to get me out, and all that did was give me permanent invulnerability.

Sigsegv error

So i opened kart 1.3 and i just get an error that says:
SIGSEGV - segment violation

This happens continually, so I get the 1.3 install file and extract it.
i open it in a newly "unpacked" game, and it still crashed.

Now this is when I'm trying to open the game in OpenGL, and opening via the EXE yielded the same results.

eventually I find that when I close the command prompt the opens when launching in OGL, before the game fully opens, the game works as normal.

But if I leave it, then I get the error.

EDIT: Oh, and if I'm playing in fullscreen and move the focus to a different window or the desktop I get the same error.

EDIT 2: And if I minimize it when its not in fullscreen I get the same error.

I keep repeatedly getting crashed by Z_Free: wrong id. Happened 4 times in one night, and has happened repeatedly before.
macOS, latest version of Catalina.

It feels like this is happening whenever I'm playing online and someone else joins that server. Usually this happens at higher player counts, something like 12-15.
I restart the game and go to the same server and notice it has 1 or 2 more people.

I dont know why, but ever since I upgraded to 1.3, loading maps takes way way longer than before. Before, it was instant, now it takes about 1 or more seconds to load a map. This makes time trials excruciating. :(

Still getting hit by wrong id. I now strongly believe it's happening whenever the Master Server updates. I've noticed when I play offline multiplayer, I'll often see a console notice (and a minor hang) indicating the MS updated. But whenever I'm online, I never see such a notice. Instead, the game crashes frequently because of wrong id.


I have the following problem: I have two computers a PC and a Laptop both connected via LAN and I want to host a LAN game. If I open a LAN room on my Laptop, I can join that room on my PC, when I enter the IP address of my Laptop. For some reason when I try to open a room on the PC and then try to join that room on my Laptop, when I enter the IP address of my PC it won't connect. I don't know why when I host the game on my Laptop it works fine, however the other way around doesn't work at all.
Does this have to do with my network settings?

Any help would be appreciated.


*insert Glaceon cry here*
Record Attack Menu Crash

So in record attack, in the pause menu, if you press confirm and cancel on the same frame when your cursor is on restart or abort, the game crashes. The crash logs for the crashes is in the last two entries in the attached srb2kart.RPT file in the google drive. https://drive.google.com/open?id=1psEnL2bVfk-KllGk5dEVeQZFv6ZRLBsv

The bug quoted above also seems to occur (on 1.3) if you try to start a Record Attack race and go back to the title screen on the same frame. This is trivial to do due to the fact you can easily buffer inputs through screen transitions.
To reproduce: boot up the game and hold Enter during the title screen fade-in, then switch to holding Escape after a little bit of it fading to the Record Attack screen, and the game will surely crash (as holding Enter not only enters Record Attack but also buffers starting a race).

So I found something stinky in kart 1.3...

If you respawn at the right time during the start countdown, you can get the best boost start and some flash tics from when you normally respawn, uh oh! You may think this would be hard to do because you have to type respawn in console, but you can bind the command to a key via kartexec.cfg. The timing is still hard, but could be learned via practice. I swear this was not in kart 1.2, but it seems like this game has more spaghetti monsters then I have realized, like how in kart 1.2, the glue on some cuts was removed.

While the amount of invincibility is not too long, it is still enough to get an unfair advantage in netgames, especially if you are in the back of the starting grid. This next comment is about a mod, but it is still relevant since it's a very popular one. This is obviously made even worse with extended flash tics from kartmp, since you have EVEN MORE flash tics from a successful timing of this bug. Like with my last bug report, I will have a google drive with a video file and the .imp file of a successful attempt incase that is necessary. It's hard to see in the video because of the numbers, but when they disappear, you can briefly see Mighty flashing, which obviously happens when you have flash tics.

For some strange reason, and this started happening last week, my game would stay frozen and not respond at all the second I attempt to launch it, with no error message. Normally this issue hardly ever happens, but now it happens on nearly every single launch attempt to the point the game is unplayable. I've restarted my PC, and even launched a fresh install of the game, but to absolutely no avail. I'm also running v1.3.

There's an issue with vertically scrolling Floor over Floor textures which contain transparency in software; the color shifts but the texture itself does not. This affects any floor over floor with a texture that has transparency. The FoFs in this wad are both scrolled with linedef type 506; the one on the left is only scrolled horizontally. This issue is also present in the current release of SRB2.


Another issue is that fake floor/ceiling planes only render correctly in spectator mode. This gif is from the fake planes example wad on the wiki. The correct rendering on the right was taken from the wiki.
