Blaze, redownload already! That one was already fixed in the reupload. You must've gotten the borked version very early.
In the current version, Ice Hockey still doesn't work, much to my dismay. (I fixed it by adding one line of code, but Mystic doesn't want me to give out patches or new exes... sigh.) After you score a goal once, the snowman becomes unpushable, so you can't do anything after that. I'm hoping I can get a patch released sometime soon to fix this, because I really wanted Ice Hockey to be playable.
Time limits and point limits don't get reset in netgames after the game mode is switched to coop or race. This leads to weird results because you hit a Badnik or the minute changes on the clock and suddenly it's saying you got through the act, when you actually didn't.
Spring Hill Zone is screwed up in OpenGL for some reason. It gives error messages and, if you aren't lucky, crashes. Neither AJ nor I has a clue what's causing this (the Nights level hasn't changed since the last demo, and it's a map problem that shouldn't have to do with the new HUD), so all I can say is play in software to run Nights.
Nimbus Ruins Zone, one of the new CTF levels, has a slightly glitched sky in software mode. It's because the map is so big, and there's no real way to fix it, but it's pretty minor anyhow, so I'm sure everyone can tolerate it.
