Paper Server, ex-Forge world - how to clean up world file and unknown attribute warnings?
I inherited server files to host for friends. Their server ran on Forge as they used a tree-felling mod, but no modded blocks were added.
I now run the world on a Paper server and added an equivalent plugin, but the console will now spam warnings about unknown attribute.
While this is mostly harmless, it is annoying to see and I think all of the old Forge data is causing random issues like people losing all xp or dying on login. In addition, I think the world files are causing a memory leak as memory usage will slowly creep up and stay there, even when all players have logged off.

Take a screenshot of your files like the folders n stuff
example of a Paper/spigot(ish) server
the config folder will likely contain forge configs that u gotta delete
I've imported only the world folder itself
Everything else is clean Paper

Alright so no world issues beyond playerdata?
You might need to use NBTExplorer and remove weird attributes from the player.dat files in playerdata
Not in-game, no
The main symptom is the missing attribute console output
As well as a potential memory leak
There will be a few weird quirks
can you copy post that specific error
One time the server ran out of memory, and on reboot I logged in with fly mode enabled (even though I didn't have it on before)
These will crop up when players are moving in certain chunks
Not all of the time
I have no idea which ones. Presumably ones that were generated before the migration
But this doesn't seem to be the case with all of them
Most of us are settled near spawn and this message doesn't constantly appear
Which suggests that maybe it's not every single chunk
can you do me a favor?
Go to playerdata and upload a single nbt file here
