[logzero]

Win7x64/VS2010 debug build. Car XS, track paulricard88.

Game will abort when hitting the brakes, must be triggered by brake lights code.

Also happened to me under Ubuntu just after loading the track before I could play.

I just pushed a change to the git repo to disable asserts for these types of simple OpenGL errors. I had those enabled when I was writing the renderer and forgot to turn them off. I will look into the cause because this still needs to be fixed, but at least it won't crash.

Fixed the real issue. The problem was just that the model wasn't being referenced if it was loaded via the content manager's cache, so it was getting deleted during the post-load sweep.
