With the most recent update, it now shows each individual outfit when trying to assign a dweller a different outfit. So if I have 25 advanced jumpsuits, I have to scroll down past all 25 of them just to get to the next type.
I've also noticed that whenever I have an active Objective that the incident occurs less often... For example, I had an objective that said "Survive 7 Deathclaw attacks with no casualties". Before I had that objective, I was attacked by deathclaws everyday and almost every time I was on the game for more than 5 minutes... Once I received that objective, I was only attacked by deathclaws once in probably 3 weeks to a month. Sometimes I would be on the game for 20-30 at a time and still only 1 deathclaw attack. AS SOON as I cancelled the objective because I wasn't getting attacked, BOOM I get attacked by deathclaws for the first time in weeks. Coincidence? I find that hard to believe. I've noticed the same thing with other objectives... Rush 45 rooms... Rush failures increase drastically... Put out 40 vault fires... Other incidents happen 10x as often... Etc.
