Weird Exanima Sound Bug - Bag sounds like zombie when walking over oO

[Excoriate]

I just encountered this weird bug (I forgot to turn off the TV, so don't mind the voices ;D):

When walking over the bags it sounds like a Zombie that just got hit. Scared the hell outta me the first time I ran into that room xD I tried tripping on other stuff, seems to happen only with the bags...
I can't provide a savegame, since I was running my autobackup tool to test something...

Here's my Logfile (Maybe consider logging more stuff while Alpha/Beta phase?!):

That's hilarious. I've always wondered what's in those bags!

I had that happen today too, I assumed it was happening off screen as i had never heard it before when walking on those bags, always sounded like pieces of concrete before today.

He fooled you all, that's not a simple bag. It is an expert ninja-zombie with special camouflage thaumaturgy.

But i discovered him:

Interesting. While I haven't had this one I have experienced some planks and doors making veryt metallic sounds when walked across or opened suddenly.

Only heard this noise while running "naked"
I'll try to recreate
