This is quite an annoying bug, especially with the longer quests.

All the quest counter resets to 0 around the time I am able to cancel one of my three quests and get my daily score.

Could it somehow be related to having pregnant dwellers? The questcounters stayed stable for the past 2-3 days until today, when i had pregnant dwellers again.

I had to do "deliver 14 dwellers " in 1 batch last time. At least the dwellers were happy.

Same here. All objectives keep resetting to 0. I had one to collect outfits at 13/14. Now is 0/14 again. It is annoying! Now I have to collect 3400 food and I don't have time to play all day long. If it does the same if will be bad, soo bad!

Also experiencing my objective progress resetting to zero periodically.
