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:

Local Idiot
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".

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.

Process killed by signal: SIGSEGV - segment violation

I_ShutdownSystem(): end of logstream.

There's the RPT file here, too.

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.


Ideally Imperfect
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.
