I went in to my test game and all benches show no thrall on them even though when you open the bench there is a thrall working on bench. The Tralls are all invisible.
I tried removing the thrall and resetting it back in the bench still invisible, tried a new named thrall in bench still invisible., if you look close you can see the hammer and the steel the thrall should be using in his hands but he is invisible.
Picked up bench and put it back down and put thrall in and there we go so it seems that all NEW and many old benches will need to be PICKED UP and put back down to reset for the thralls to show up in them at the moment.
UPDATE: Fix of picking up bench and relaying it down does not work though game reboot. I restarted game too a break from testing and came back to this, had to pick up the bench yet again and replay it for the thrall to show up in the bench at first he was invisible again.
Before I logged off
After I rebooted the game.
