FWE v. 6.03 already have a "refilling scripts". Obviously, it cause troubles. It's very peculiar to be honest. For example, after drinking a Purified Water you'll get "Empty Soda Bottle" from "Bottle Refill" mod and "Empty Bottle" from FWE. This patch can be fixed by deleting FWE scripts on all bottles and adding an "Bottle Refill" script to all drinks encountered in FWE.
