This bug I had for sometime, but I thought it something that will go with time, But no... When I send a dweller to wasteland nothing happening, he just ran for hours and nothing I tried to send few dwellers but same result. Someone have this problem or it just my game f*ked up?

I need help here because I paid money on that valt.

Did you for any reason change the time and/or date on your device?

Yes, I did. To speed up some dwellers training, but I notice it ruining my resources time collection so I changed the time again...

Right.. Should've read up on that first... One of the dead giveaways usually. Just wait until your game reaches the time you forwarded to. So if you set it 6 hours in advance, wait 6 hours. If a day, a day. Etc. If you run out of resources in the meantime, rushing a room will reset that room. So rush everything. And dwellers in training need to switch rooms for a bit to start training again.

Thanks. Hope it works
