Hi hello! I'm not sure if you'll see this so I can always reach out via DM in case this gets missed.
We did a bunch of digging on this for you and thought it unusual because we didn't have a bunch of other UIMs reaching out with similar. After asking the team to take a look, it looks like your loot piles had ~10 minutes left on your last logout, and we suspect that your deathpile tracker plugin might have been out of sync. When testing manually using a copy of your save before that last logout, your loot pile with the Shadow despawns within 15 minutes, with the other two despawning within the next couple of minutes - as opposed to the ~40 minutes that your plugin is indicating.
Additionally, when poking around it looks as though the actual locations for the deathpiles are different from the tiles that are marked for Deathpile in your screenshot, which leads us further to suspecting that it's potentially a plugin desync issue.
In this instance we believe that the issue here is user error and not related to yesterday's game update, but I am genuinely so sorry for you having lost such an insane set of items on your UIM :/
