After clicking "Quit Game" from the system menu, the window blacks out (as usual) but instead of returning to the login menu it just crashes with a "MapleRoyals has stopped working" message. I tagged this bug as trivial since this only inconveniences me with a slightly longer login time when switching to other characters in the account.
Assuming this happened after exiting your storage, it's a known issue with inventories over a certain amount of items.
Yes, this kept happening as I was transferring a lot of items between two of my characters via Storage.. Hopefully it will be addressed at some point, thank you for the clarification.
If I know I'm gonna be doing a lot of transfering or searching through storage, for the mean time I just per-empetively open up like 10 clients lol. Not ideal but it works for the time being. It is an annoying bug.
