I was wrong, I used the 1.10.2 version of Spigot/Bukkit.

PS : Sorry for my bad english, I'm french

I am having this exact same issue, was a resolution ever found? I am only having this problem with end portals

I created three new worlds on my server:

world_2

world_nether_2

world_the_end_2

Then I linked portals with the following commands:

/mw link world_2 world_nether_2

/mw link world_nether_2 world_2

/mw link-end world_2 world_the_end_2

/mw link-end world_the_end_2 world_2

I located a stronghold, activated the end portal, then jumped in. The result was a bath in lava and the following error repeated endlessly on the console:

https://hastebin.com/qivubigihu.vbs

Server: Paper 1.12.2 #1244

Multiworld 5.2.8

My config: https://hastebin.com/inozugocum.bash

Thank you in advance for your time and effort with this issue. I am running all this on a test server, duplicate of my live server, and thus would be glad to do any testing needed that might help.
