This is extremely odd, I've done everything I can to replicate the error that you're encountering , and yet nothing seems to occur on my side.
I have tried paralyzing everyone individually including Su and using every item in my inventory.
My debug window hasn't prompted anything that produces the error too. I'm slightly at a loss to what is happening here.
The jump for the enemy didn't show any bug report or otherwise, which will break the game or display an error.
Slightly confused as to why you're getting this.
If possible, could you send me your save file and I'll see if I can replicate this on my side?
