My objectives keep on resetting before I get the chance to complete them and this has been happening for a while now. For example I currently have send a dweller to the wasteland for 28hrs and it has resetted about 10hrs in. This happens very frequently for me, and sometimes the objectives reset daily. This has made the objective for surving deathclaw attacks impossible

Yeah it's happening to me to. It's very annoying when you're about to complete a difficult objective like survive 7 deathclaw attacks with no casualties. Well I literally haven't gotten any deathclaws for over 2 weeks now. No joke. If that resets on me if I get progress done, I dunno what I'll do. They need to fix this.

This happens almost daily. It just happened again. I had a quest to explore wasteland for 50hrs, and made it to 30hrs then it reset the objective and all my dwellers in the wasteland are lvl 50 with perfect stats and the weakest weapon is a plasma rifle
