Hearthians dont build after sleeping

placed down the shared sleeping quarters (though does it to all buildings) and after spending a day building my hearthians went to sleep, then when then got up in the morning they wouldn’t continue unless I saved, exited and re-loaded the save.
also when I re loaded the game I got these 3 errors:
1)

develop-2881 (x64)
...ehearth/renderers/fabricator/fabricator_renderer.lua:23: assertion failed!

Steps to reproduce:

  1. load game, place building, let hearthians go to sleep (like I have a choice)
  2. notice hearthians are on strike, save game, exit to menu
    3)re load save and see hearthian strike was ended
