Plutonium

Why would Plutonium make you crash on purpose? Especially for something like picking a weapon, why would we care that you play a certain weapon?

This is a known issue. Either don't pick it at all or look on the forum for a temporary fix

Camper1988 change your resolution ingame to your monitor's max res. Then in the the console type in writeconfig conLZM.cfg. If affects don't apply immediately, restart the game.
