If you delete the living quarters that your pregnant dweller's baby was concieved in then she will remain pregnant.... forever. My dweller has literally been pregnant for days. I am wondering if there has been any solution for the bug. If anyone knows a REAL solution besides "1) rebuilding the living quarters in the same location 2) keeping the happiness level up and 3) leaving her in the living quarters", as none of those have worked for me, then please let me know!
