So, what you're suggesting is having that 'breakaway' mechanic incorporated with a new piece, and the collision issue fixed? I'd like something like that! You could designate rockets to the number keys, activate them when needed, and the pieces connected by a breakaway could fly off with the rocket.

I haven't had that issue myself, but I definitely understand why someone might. =)

Hmm, I was able to login; is there a chance you're running 0.4.2 and not 0.4.2a?

Just wanted to confirm that I've also had this happen.

Yeah, noticed that too; thanks for mentioning it! =)

How else might you expect the wheels to interact when placed like that?

Yeah, my graphics card (Radeon HD 6850) occasionally seems to have a hard time with it. Before playing Crashtastic, I had never seen my card temp. rise above ~55°; with Crashtastic, I've had it running at 70°+ (100% load, 2200RPM fan speed). o_O What. Anyway, I'm sure things will improve. =)
