I will test this in a single player and a clean server, but the original was a vanilla server in 1.21.6, then updated to a snapshot (between 1.21.6 and 1.21.8 I can’t remember) and then a spigot version of 1.21.8 and finally the snapshot 25w35a.
I did some more testing and a bit of research, I found some information on upgrading from vanilla to spigot and the nether. I would assume that the same problems can occur when switching the other way.
I believe this is an issue with the spigot/vanilla transition and not a bug in minecraft. Thank you, and apologies for wasting resources on this. This can be left as closed.
