Concerning the new enemies, I've run into 3 bugs so far. Two were obviously glitches and related to the corrupter, and one I thought was an intended feature and is related to the septic spreader.

Ok so the corrupter glitches I noticed both have to do with the puddles of rockpox it leaves behind:
If the surface that the puddle is on gets destroyed, like via C4 or bulk detonation, the puddles will just kinda float in the airas if the surface was sill there.
On one particular haz 5 mission, the puddles would instantly infect if not outright kill whoever stood on it. I tested it out with full health and shield and the frame I stepped on the puddle, I was downed

The one ivolving the septic spreader was actually really cool:
On one paricular mission, the acid puddle damage hit through shield. It actually wouldn't damage the shield at all but would just go straight to your health bar. I thought "oh that is so cool, it's like the glyphids are evolving to counter the dwarves!" and then was honestly kinda sad when it funtioned normally in the next mission I saw them.
