I will start in the order all this started.
1. The other day I had a dweller in the wasteland hoping for good loot. He had been out for almost 50 hours and he was down to six stim packs. I was wondering if he would last while I slept or if I need to call him back. I decided to wait a hour before I went to bed to make the decision. When I was checking on him I noticed it was saying he had only been out there for 12 minutes. I was thinking waiting 6 minutes is better than over 24 hours. So I called him back and instantly I had the option to claim the items. So I did and loaded him with max stim packs and radaway and sent him right back out then I tried to go to sleep.
Two hours later I was still awake so I checked on him and he had a blue outfit which is rare for me because I only got three blue items on the last run so getting one first seemed odd. Then I looked up and noticed it said he had been out there for 106 DAYS! (That explains the blue loot.) I let it ride but I am not wanting to wait almost two months for him to return but I am getting good loot so I will just take the bad part of this glitch with the good. Not like there is another option.
2. A couple days ago I noticed the radio room (two joined rooms) had 2143 days until it called for people to come to my vault. It had two dwellers in there with a total charisma of 25. So I added two more dwellers to the radio room with a total of 23 charisma. That put the room with a total of 48 charisma and it said it would take just over 1000 hours.
I tried pulling everyone from the room and putting them back and it didn't change.
3. (back to the first issue) Last night the first dweller had "been in the wasteland" for 111 days. I woke up this morning it said he had been out there for 106 days. Nothing I could do so I let it be.
4. Today I was playing the game like normal collecting utilities and leveling up dwellers until I had to run some errands. When I get back I start the game up and none of my utilities were ready to be collected. This happened once before so I closed it and reopened. When it had loaded it still wasn't ready and I was looking and noticed that ALL rooms had a wait of 19 hours and 32 minutes! Most of the rooms have at least the SPECIAL stat of 8 for the dwellers in them if not more. Most have 10+.
Is anyone else having any issues like this? I have read a few pages in the forums here and I haven't seen anything.
