Sorry for not answering earlier, I had a very busy week.
Anyway, now all the reported bugs should be fixed... Well, except for the non-existing Incendiary rounds for the Light Cannon, as it's not a bug, it just hasn't been added yet.
It looks like you can't access a MC'd zombie trooper's inventory normally. I had to do the old trick of going to someone else's inventory and scrolling.
You mean after its weapon was ripped from its body? If yes, then it's as designed.
