It seems to be the only mod giving an issue, I'll see to re-download the mod and if that works I myself will close this one.

(for extra info: I made a world, played on it 2 times and had a rat that I made a fisherman and made him put items in a chest, I did, by mistake, clicked in another chest, way out of reach, with the cheese wand, thou that didn't change the rat's behavior, so I thought it didn't count, I still think that it didn't count, but who knows, I tried 3 times to run the world again and nothing)
