"Issue experienced: loss of skills with incarnate and locking of skill bar for remote player. Both work fine when a player is invited with the hot fix. However, on reload the issues crop back up. "
I encountered the same problem.
Seemingly random skills get removed from bars.
The summoning skill tree isn't really useable atm due to the fact that it's not possible to access incarnate skills other than if they are allready in the hotbar.
