Context: I mostly do settlement building. I run around booty cheeks out to the wind because it makes things easier (specifically the glitch for lowering settlement size.)
Fast travel to Zimonja.
Hear death claw noises and "yer fucked m8" music.
Slam ESC.
Scream\laugh because i had just been thinking to myself how funny\terrible it would be if something like this happened.
Alt+F9 to record because of course I'm gonna record my naked ass sprinting away from him
ESC again and book it into the crowd of settlers spraying bullets at me and big lizard.
Never seen a death claw up there before in my 500+ hrs on this game.
It doesn't have to be just guns either. It has to do with how many polygons the item has - i.e how complicated the item looks. A basic wooden box is going to make the size go down less than a super complicated looking gun, piece of armor etc.
