Chest bug

[Aevumas]

It seems that this pops up only once you've opened quite a few chests.

The client crashes on chest open:

I also noticed that drop quality increases as you progress, then items stop dropping, just lots of gold.

When I play next, I'm going to count the number of chests I open before it crashes. If there's a fixed number per level, I should note that it happened two times in a row for me as the last chest on floor 5 when looting everything, so maybe that's the magic number.
