Want to report some success with the hot fix.
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.
Workaround: both drop game, host loads game, then invite remote player. I am not maintaining that this is the only way to reset the issue as the cycle could be the remote player drops prior to reload, reload the game, then re-invite. There is an issue with the reloading and remote players. Sometimes the game crashes and will not restart. When rebooting host, a warning from Windows 10 says that it has a process or bad memory issue that needs to be shut down.
