Details

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.

Description
The player hearts is simply not synchronized between worlds

Steps to reproduce
just create a new world with mv core, create group with mv inv and put every worlds in this group by sharing everything between these.
Go in a world, lose damage by fall damage or anything else ans teleport to another world, player hearts will reset.

Expected behavior
Player hearts need to be sync with other worlds, my server its an UHC SMP server with no natural regen, so it's a big problem if everytime player can reset their hearts by crossing a portal to tp to another world.

Screenshots
i made a little video to show the problem : https://youtu.be/AtzGagqGBQQ
