I expected that a paralyzed statue wouldn't start walking and slamming me around. I was very wrong. I also doubt that this is intentional, though it was amusing.

Interestingly the trollager seemed intent on walking back to the exact spot where it initially froze. This was after bouncing back after being hit with my pickaxe.

On further testing he wasn't moving back to where he froze. Just moving and attacking while nudging into the wall behind where I died in the above picture.
Once again this was only after I provoked the statue.

Hmm I think that's only outside of dev environment which is strange... will look into it. Thanks for reporting!
