Expected Results: To be able to exchange Dungeon Marks for higher tiers and chests

What actually happened: Would get “Resource Error” and the game would crash when attempting to exchange Dungeon Marks for higher tier marks or chests. After re-opening the game after the crash my dungeon marks would be gone causing me to lose hundreds of dungeon marks…

How often does this happen? When did it begin happening?
Is this a once-off issue or has it been a consistent issue? Does it only happen in specific circumstances?

This happens about 30% of the time I attempt to exchange dungeon marks.

Steps to make it happen again
Please detail the steps taken to trigger this bug. The more detailed the breakdown, the easier it is for us to test in-house.

  1. Finish final dungeon farm of the day
  2. Open shop
  3. Attempt to exchange dungeon mark for higher tier or chest
  4. Receive Resource Error followed by game crash
  5. Re-open game and shop
  6. Dungeon marks have disappeared

I’m currently following this up with the devs.
