The latest version of ImmPtl does not change the client player world when handing redirected packet. (Keeping the player dimension fixed will make mods able to see whether it's processing a redirected packet)
In https://github.com/OnyxStudios/Cardinal-Components-API/blob/c29d5bd7e0b472c99489157ca0ac26e09abcd055/cardinal-components-entity/src/main/java/dev/onyxstudios/cca/internal/entity/CcaEntityClientNw.java#L50
It uses the player's world which may be wrong when immptl is handling a redirected packet which may be wrong. It should use client.world directly
