I've set up a host of simple rulebook rules for adding things via a channel, like /1face adds a facial animation HUD. I've noticed new ones I create don't seem to work after saving and updating the ruleset to the HUD. I've counted and it appears any rule I create after rule #20 in a ruleset does not work. If I move that same rule up in the order it works just fine. Is there an unwritten limit on the number of rules withing a given ruleset?
