Try to play around with the client settings.
!!! And make a hotkey on the “Return” command for the thralls - this updates thralls “Combat cycle” when they return and put away their weapons.
ESC - SETTINGS - CONTROLS - top-left “COMBAT” - scroll in down - bind “Command RETURN”.
Of course, this is not the solution to the problem - the problem is in the Funcom. This is just an attempt to make a crutch.
