Yeah, the physics vehicles have a limit of 20, and it's hard-coded to be un-hackable, so you cannot get by the limit.
Also, this happens to my desktop when it's up for roughly about 10 minutes.

But it's only on a limited area, then the graphics card totally gives out.
EDITKapturrith is vewwy sick.
Somebody cheer him up. :(
I was incredibly sick yesterday. My spine was so tense, it hurt to move. It was so cold when I went to bed at night, I nearly felt like I was dead. I'm O.K. now, though, but I didn't come to the internet to plea for sympathy.
Also, I came up with this in my head. If you've used the "Russian Soundboard", click the one that says "I hate cats". This is what it's based off of.
I hate Kap. He's all un-fuzzy and stuff.
