Was finishing up Temple of the Moon

Realized I only had 2 bags on me instead of 3.

Went back to look at video capture and noticed one of my bags disappeared sometime after I dropped a bunch of containers on a pressure plate and picked them up a minute or two later... didn't notice it was missing at the time.

Is there any way to get this bag back?

edit: found the precise moment I think it disappeared... on the upper floor there is a small hallway with a boulder that rolls back and forth... when I tried to drop the bag that is now missing on the plate, it happened to be right when the boulder rolled over the pressure plate. And it looks like that's when the bag just disappeared into nothingness.

edit 2: Managed to reliably reproduce this, see here: this video. It seems to require that a Soul House be one of the items you muck around with when dropping stuff onto a pressure plate.

Still haven't figured out a way to get the items back.

AFAIK the best you can hope for is to reload from a previous save; the game's kind of glitchy in places like that. I searched a little to see if there were any cheats or savegame hacks, but all I could find were ones for character stats, not inventory.

There can only be a certain number of objects per level of a dungeon, so if you drop a lot of items at once, some might despawn.

It's generally better to use block figurines or rocks for pressure plates, for that very reason.
