Game freezes when walking through a custom portal

Status

Fixed

Issue description

When walking through a portal to a custom dimension, The game gets stuck on "Loading Terrain" and requires a game restart.

I previously updated to version 2020.4 from the 2020.3 version of the game to fix the issue #61924 that 2020.3 had.

Issue comments

I need a FULL crash log from the console tab and workspace. Check the rules for more info.

You are using 1.15.2-forge-31.2.29 while MCreator is currently designed to work with 1.15.2-forge-31.2.0.

Tried running the mod on forge 1.15.2-forge-31.2.0, The issue still remains the same though.

Another log file if its useful: https://pastebin.com/VjzmhE44

Also probably useful, The mods runs perfectly when i start the game via the play test button within Mcreator. But not the exported version (ive also reinstalled minecraft and forge a few times just in case it was a broken download or something)

Yep can confirm this, I will do some testing.

This is present in 2020.3 too.

Marking as major as this makes 1.15.2 dimensions useless. I will fix this in the next snapshot.

I made a dimension and it didn't crash. Then again I used a procedure
