Ive been running an ATM7 server for quite some time now, and was messing around with the alfheim portal in creative mode. Managed to teleport to friend who had completed the requirements to enter the dimension and the swirl does not go away. I reset my advancements to try and match hers but even deleting the player data from the world file does not make the swirl go away. Any help would be appreciated.

Nevermind, restarting both client and server corrected it. Sorry!
