Bug Description

Original bug was that parrots could not be named after switching worlds, reported it in Discord and was instructed to open a bug report. When attempting to recreate it on a blank server, this issue came up. The parrot becomes invisible after teleporting to a different world and it tries to dismount.

Agreements

• I have searched for and ensured there isn't already an open or resolved issue(s) regarding this.
• I was able to reproduce my issue on a freshly 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.

you may want to retry with the latest papermc, it seems to only disappear after you go to creative mode, which doesnt seem like any relation to multiverse.
