Noticed this a few times. When you have an Objective that asks you to update dwellers stats or send x amount of people out to the wasteland for example.


If you do muliple actions that will update progress of the object "too fast", it doesn't register the actions properly.


I spotted today I was asked to level up 12 dwellers specials to get a free lunchbox. I tried clicking on two dwellers that had reached the next stage of agility in fast succession. There was no pop up to say my Objective updated.


Seen this a few times. Annoying.
