Immersive portals crashes when using FreeCam and tweakeroo

[iainvm]

Minecraft Version: 1.18.2 Immersive Portals Version: immersive-portals-1.3.3-mc1.18.2-fabric.jar Free cam mod used: tweakeroo-fabric-1.18.2-0.13.1.jar Link to other mod: https://www.curseforge.com/minecraft/mc-mods/tweakeroo

When near some immersive portals if I enable Free Cam (Spectator like mode) the client crashes with the following stack trace

This also happens with other free cam mods like: https://www.curseforge.com/minecraft/mc-mods/free-cam

Seems that it creates a faked camera entity and the camera entity's world will be different to the player's world when multiple client worlds are loaded

I was having problems caused by the same issue but it didnt result in a crash ever. What happened is I would fall through the world when going into free cam in my single player world.

This doesn't seem to be an issue with the community built 1.19 tweakeroo and the latest immersive portals.

Even though the community version of the mod is accepted and might not have the issue (I haven't tested). I wouldn't say we should close this issue based on it, since the official tweakaroo is being rewritten and could still have issues when officially released.

Though very useful to know as a work around.
