Good day, I just noticed a problem with the thralls and that is damaged building is set to certain times and the thralls react in this time not even on enemy players once seen that the aggro range is too low. What an extreme problem is when you have to secure certain points with archers. In addition, the thralls do not move back to the starting point, after an attack or no longer respond to enemies. In the mom you have to defend your own base without help.

Steps on how to reproduce issue:
1.In raid of free time near a base go the thralls do not respond at all the purge only actions if the player attacks or is attacked
3.Thralls can be lured one by one from the base and die by fall damage
