High Disappearance of half of inventory.

Description of the bug: (optional screenshot/video): I was in FM2 and had set up a store selling scrolls from my whole inventory that included, Dark 30% Knuckler ATT, Dark 30% Overall INT, 60% Gloves ATT, and a Chaos Scroll. I left my MacBook on while the store was set up and while I did, my Mac had went into sleep mode. When I turned it back on MapleLegends had exited me out. I logged back on and all the items I had from the shop were gone.
What is supposed to happen?: All of it was not supposed to disappear.
Where did you find and/or notice this bug?: When I logged back in.
A step-by-step guide to re-producing this bug (optional): Set up a store selling items, have the system go into sleep mode, and log back in.
Extra information (optional): Sorry, this was all I had on it for now. I'll see if I can get a video of me reproducing the bug.
