We updated to jumpgate the other day, and we're having a problem where the tokens randomly duplicating, creating phantom unusable copies. We're having trouble replicating it, but it has happened with two if my players. The tokens it happened to are slightly smaller than a 5/5ft square, but that may be a coincidence. Reloading seems to fix it, but we're concerned about it effect combat (Specifically with a large number of monsters) as a player seeing two versions of the same monster would make combat a little harder.
