Permission based limits will now look at the highest number per block (if a player has domain.<blockname>.limit.2 and domain.<blockname>.limit.3 [and appropriate setup in config]), it'll now only use the 2 if it can't find a higher number. In some cases it was looping through the permissions and applying the 2 after the 3.
1.16 prep continues - I'll be working to get Domain 1.16 ready as soon as the jar drops.
