I have a skyblock server, and I wanted to make a custom nether with worldedit. I did so in a singleplayer world, then uploaded the nether world into Aternos. Now, when I load the world, I get an error message in my log (click link to view the error).
Paper server log [#BISo2Uk] - mclo.gs
I've tried the first solve method, deleting the file "World_nether/uid.dat" by clicking on the button next to it, and a checkmark pops up but the error persists and the check goes away after a few seconds or when I reload the page. Also, when I exit the game in the nether, I spawn in the overworld at corresponding x and z coordinates with the same y coordinate. Any ideas on how to fix this or why it's happening? Thanks!
