Inventories randomly split between dimensions

[VL4DST3R]

Describe the bug More than once players (and myself) have noticed both inventory wipes and inventory separation between overworld/nether/end for a particular world.

To Reproduce Steps to reproduce the behavior: Behavior is random as far as i can tell so it cannot be reliably reproduced. That being said i have some insights about the issue and a way to fix it when it happens. See below.

1. It seems to occur when closing/opening the server, never mid-session.
2. Plugin reports no error of any kind, even with full logging turned on
3. The issue seems to affect the world/dimension as a whole, in the sense that once the world is "bugged" any subsequent players that join said world are also affected by the issue until its fixed

Expected behavior This to not happen? :V

Plugin version

• [x] Using the latest released version of the plugin
• [ ] Using the legacy jar

Server version This server is running Paper version git-Paper-138 (MC: 1.16.1) (Implementing API version 1.16.1-R0.1-SNAPSHOT)

Additional context and logs To fix it, i had to do 2 things:

First, the world:

• rename the afflicted world to something else to remove it from the multiverse list of maps
• re-generate the map with the original name/seed
• transfer the map ..\DIM\region data from the previously corrupted map to the newly generated one, keeping everything else as-is.

Then, the plugin:

• navigate to the server ..\plugins\PerWorldInventory\data\UUID_of_the_affected_user(s)
• notice how now you have instead of one world.json file per "world set" you instead have a world.json and a world_the_end, essentially treating them as distinct worlds with separate inventories.

Since this project seems to be dead/abandonned, ill leave an updated method to fix this if someone else stumbles over this place.

Turns out all the level manipulation is not needed, instead closing the server and removing the wrongly generated _nether _the_end files achieve the same goal.

Also logging out on anything else other than overworld seems to exacerbate the issue, but still not reliably so.
