What you were expecting to happen, and what actually happened:
When I start a Delve, then leave and later return to it, all the rooms seen void and unclickable, even if they are not completed. You can only end the Delve with whichever chest level you have at that moment.
How often does this happen? When did it begin happening?
3-4 times in 2 weeks
Steps to make it happen again
Start a Delve, exit from the game, return to the game. Doesn’t happen everytime.
