Fiddled around in Sandbox multiplayer for a while and crashed

Okay I think I'm able to pinpoint this, it happens when you spawn the L4D2 Tank NPC from the entities list and switch to the toolgun. Guess the author didn't test it enough, plus it tanks performance (pun not intended)

Tried setting the shadow quality to low when playing sandbox on flatgrass

crashed adding wheels to my burger car

Got this one after maximizing and restoring down the game window 

Was trying to tie anime girls to a crane to joyride it around in but spawning it in crashed the game, unacceptable

Turned post-processing in the settings menu from low -> high. Game instantly shut down.

I suppose a reason for this crash, one of many is repeated toolgun use. Was making an armored dynamite SUV and it crashed
