Details

I was able to reproduce my issue on an unfreshly setup and up-to-date server with the latest version of Multiverse plugins with no other plugins and with no kinds of other server or client mods.

Description
when going through the end portal, last_location takes players to the last location of the players in the overworld when going back as their last location - creating a loop.

Steps to reproduce
jump into the end portal and jump back up from the other side when last_location is enabled

Expected behavior

Vanilla behaviour that overrides last location when coming back from the end Screenshots
