LibreExpFix

Good news, the bug is fixed on 24w20a (1.21)

NOTE: This mod support both Fabric-like and Forge-like loaders! Click here to see all versions because CurseForge's sidebar is trash at showing each loader's jar file!

A small mod that fixed experience bug after teleporting across dimensions, also fix other issue when you teleport between dimensions (MC-124177). So small that you don't even need FabricAPI!

You can test if this mod working properly by creating a superflat world, fly or teleport to world height limit (if needed place a block there) then execute these sequence of commands:

• /effect give @p minecraft:night_vision 99999 1 true
• /execute in the_nether run tp @s ~ 10 ~
• /execute in overworld run tp @s ~ 10 ~
  If you still have night vision without having to wait a few seconds (or experience doesn't disappear), then the mod is working.

Note: This mod should work with any version newer than 1.18.

As the name suggest, you can use/do whatever you want with the mod... Add it to your modpacks or something, go ahead... It's also not opt-out from third party distribution, that should helps your players a bit from CurseForge's hell. Also check out my other mods while you're at it, that's more than enough to "support" me
