1. I use the anarchy blaster stamped twice on my outfit. It looks fine when I first save it, but if I change or reload maps, one of them is missing the holster. This also happens if I use anarchy with mischief. It does not happen when the weapons are not stamped (at least for me), so I know it is related to the outfitter itself. This likely happens with any sort of weapon with a holster.
2. Some weapons with lights on them z-fight with the base weapon mesh. These are slapped-on glowing textures that fade in and out. Some weapons included in this are: Anarchy and Defiant Technographer's blaster. They both appear to use the exact same fading texture.
