I'm sorry for the late reply. Can you elaborate on what you mean by "guards on top of each other"? Did you mean the Guards in the Glitch City, or perhaps you meant the regular enemies in the Arenas? And for the weapons' visuals, this is intentional.
the prision guards of glitch city, yeah, had they spawn one inside or on top of each other two or so times.
also I never realized the weapon "glitches" before, maybe they were not so prominent, and are stronger in this patch? anyways it's only minor stuff, it's alright.
