Is this a bug? Why my mask broken?
Probably with a Total Makeover Kit. It looks like you made the “crown” or crest of your forehead just a wee bit too broad.
You’ll get clipping issues like that with certain masks and headgears. Had that problem with the engineer goggles.
Shrink it a bit and it shouldn’t glitch through like that anymore.
I have a problem with one of the mask skins for my ranger, my nose sticks out a bit
