Ever since the new update my people from certain rooms have been flying through ceilings. I've noticed that it's certain rooms that do it.

Im having the same issue. Also, when I assign them to one agility room, they pop up in the other agility room. But it says they're on a coffee break because the other agility room is already full.

I have the same issue. When I assign them to the agility room on 11th floor, they float to the agility room on the first floor. And when I assign them to the agility room on the left side of the 11th floor, they just appear in the same agility room on the first floor. And I believe the agility point is not increasing during the period.

I'm having a similar issue. Dwellers "walk" vertically or diagonally up and down. It's the "invisible elevator & escalator" bug. I haven't figured out what is causing it. Tied to a specific room type or position, Dweller, "job"?

Same issue. Raids and Radroaches are crippling

So for me it was mostly attached with the agility room but I did notice some other strange activity. I deleted my second agility room and rebuilt it in another place so far so good. I've got my hopes up for now.

I have the exact same thing and it's again the agility room there is problems with. Will there be an update to fix this?

I don't want to delete the room and try again as I already invested around 20k for this room.

This happened to me too. Happened after I upgraded a second athletics room. I deleted and rebuilt the athletics room and rebuilt it, did not fix the problem. Dwellers are still floating through floors between two athletics rooms.

Flying through the floors and ceilings hmmm...its fun and ive done it a couple of times so im talking from experience

I am having this same issue, my dwellers are flying between my two dinning areas. Raiders and radroaches fly the same as well. Really frustrating because they quickly go from one room to the next and kill my dwellers before i can even react. I have lost 12 of my 29 dwellers within 5 minutes from this. I havent been back on the game since that happened for fear of losing it all. I managed to screenshot it happened before the disaster struck. I cant seem to figure out how to post these screenshots though...
