Just saw this exploded cop car driving around after sending not-glados back to delamain. Also had a whole cool car chase followed by a bike crash when taking that one cab slowly back to del though and another took me past the the car I'm driving so huge improvements overall.
Had one random car explosion bug so far. A truck decided to stop (or spawn, more likely) on top of another car. Even the explosion didn't move the truck.
But other than that its been bug free. And this time its performant enough that I can enable a few raytracing options.
