[Davisiiiik]

Minecraft's Version

This server is running SlimeWorldManager version git-SlimeWorldManager-15672 (MC: 1.20.4) (Implementing API version 1.20.4-R0.1-SNAPSHOT) (Git: 4da075b on paper_upstream)

Plugin's Version

SSB2: 2023.3-b124 ASWM: 2.10.0

Describe the bug

As you can see in the image bellow, Ender Portal to Overworld is generated shortly after entering The End for the first time (there is a small delay, when player teleports there and then it is generated afterwards).

This issue is not happening, when you are not using ASWM (Tested on the same version of Paper and SSB2).

To Reproduce

1. Install ASWM server using this guide (download latest version here) with SSB2 plugin and ASWM module.
2. Enable End world, unlock it and enter it

Additional Information

Also tested on blank server with only ASWM, CMI and SSB2 installed
