So...I haven't read any posts describing this specific issue, but I didn't go deep into the pages, and I am not sure if there is a search for specific topics, but I digress...

One of my larger vaults, has a radio timer (when I noticed it) of 246 hours...6 dwellers in the 3x wide fully upgraded room, all in sixy sleepwear.

246 hours? Seriously?

Every post I found on google, states in increments of 12-24 hours.

Again 246 hours?

It's not like i don't have the living quarters to stable the new dwellers, and I am in no way even close to the cap...I think there's like 66 dwellers.

Am I missing something?

Did you change your device's or PC's clock and/or date at any time? Doing so will eventually break the timers in the game.

Nope, haven't changed anything.

Only thing I could think of, is I copied and moved that vault to bluestacks , on my pc, before there was actually a cloud. The issue however, is on the original (tablet), so shouldn't be affected... unless it's somehow conflicting with two identical vault numbers?

This, and the scavengers not returning with any items started when we changed from DST... I tried turning back but even after 2 days, it's still not fixed. :c

I'm having a similier issue. I haven't changed times on my tablet. But mine was up at 1564 hours. I hadn't played the game in a month or two. When I came back, the radio room timer was crazy. Same conditions created it too. Fully upgraded three wide room with 4 dwellers with each having 13 luck. This was a month ago roughly, since then the timer has gone down to 645 hours.
