I have a problem. My builder lense keep dissapeared. I downloaded it via the steam wprkshop and at first it worked fine. After a restart it was gone - however there is one lense now with a weired name but doiesnt do anything. So I downloaed the pack again but not via the steam workshop, followed the instructions, deselected the old lenses, accapted the new lenses and it worked again. However now after a restart it fails to work again. And this applies to the workers lense only. Anyone had this problem before ?
