Noticed two bugs of the same type the first 10 minutes I played on your server .
(1) Bears were actually able to swim instead of standing at the end of the ground/water border like every other beast.
(2) Wolves or any beast should automatically stop following you once you reach deep water = you should go out of combat . Howerever thisi s not the case ,because the animal continues to follow you on ground and you get stuck in combat .
