Hey, I have a Marlith pawn (named Banastra) who's roughly size 2 right now, but Swallow can't seem to hit anything. My pawn will jump at the target, but on landing it doesn't do anything. It's the normal Swallow from the Abilities list, not the one in the Slime list. I tried it on a Nisse and an iguana both to see if either would work, and it throws up some error messages:

Those are the error messages for the iguana. Any idea what's causing these issues? If it's a mod conflict I can remove the other mod... But I don't know what's causing it.
