for some reason, the viewmodels for every playermodel flicker
the ungodly part is that for SOME reason this doesn't happen with the physgun, and it only affects the gravity gun when it's equipped (not the arm)
but literally everything else rapidly flickers in and out of existence
yes, i've already uninstalled and reinstalled

***EDIT***
it just
started working
i used alt-fire on the gravity gun in an invalid spot and then the viewmodels fixed about a second later
i have absolutely no idea wtf just happened but ok

EDIT 2
further testing reveals that right-clicking with the gravity gun in an invalid spot fixes the viewmodels
i repeat: wtf
