I usually save up my gems because I'm a hoarder and I love opening multiple chests at once, but sometimes when I buy a bunch of chests in repetition the chest won't flash and disappear, effectively freezing my game in that window, because the close button doesn't work either.

After having had this several times, I managed to sorta be able to reproduce it, and it seems to only happen right before a level swap, which is usually right after an autosave.
The only thing I can do to fix this is restarting the game, which is... well, it gets really annoying.

Could this be fixed? A timeout mechanic is probably a good idea. Or even better, can you add an option to buy multiple chests at once with gems and event currency? This would save a lot of time and frustration.

sounds like the issue ive reported but everyone in my post claimed to not have the issue.

i suppose autosave could be the issue....because i know turning off auto-progression isnt the answer.

i have 21615 rubies to spend/play-with when they think they have fixed the issue.
