> guards will randomly unassign themselves and go in coffee breaks, and/or swap with random other dwellers in the vault. This usually occurs post deathclaw attack. Most "severe" case ended up with one guard three floors down wandering around, and another ending up in a living room 5 floors down, with a vault dweller from the cafeteria 1 floor down taking her place in the vault door room. All of this immediately after the position "reset" following an incident.
> objectives resetting. I had a particularly irritating case where both my "fires put out" (7/14) and "incidents stopped" (~17/30) both reset to 0 for no apparent reason. These had been accruing over a couple days of play, and occurred after ~1.5 days post update. Really irking seeing as the latter has a lunchbox reward.
> deathclaw incident timer going haywire. Seeing as the closest incidents I'd had together prior to the update were generally a couple minutes (barring self-induced incidents from rushing), I'm fairly confident something is wrong when on two separate occasions I've had multiple rapid fire deathclaw attacks. First was a series of four, generally ranging between 1 minute to 2 or 3, and the most recent quite literally being an ending of the first event, ~10-20 seconds of stimming damaged dwellers, then another deathclaw attack occurring. Combine this with bug one for rather large problems.
On a final, non-directly bug related note, I will state that I find deathclaw attacks in general to be excessively frequent. I enjoy fallout shelter as something I can do to pass the time when I have a few minutes, on the walk to work, etc., because it easily fit into those windows of time. Deathclaw attacks, however, take a considerable amount of active attention and time to deal with, and if one occurs just prior to my needing to get off the device, can cause significant gameplay issues (since sometimes incidents pause when the device is out in sleep mode, other times not, but that's a different problem). Due to this I've probably had to cut out at least a third or so of my play time of the game, and diverted to others, simply because I cannot afford to peek into my vault in the walk to work for fear my couple minute viewing turns into a 10 minute drawn out session.
