when i had the aether working i did not have cumulus menus mod installed, i only added that after i added AoA and got the error because i thought missing cumulus latest version was the issue

Could you try the build of Aether from this message: The-Aether-Team/Cumulus#22 (comment)? I've yet to release it but it might either result in a fix or a more clear log with the issue.

should i try it with or without cumulus

Either works, the version you downloaded is packaged in that build of Aether so I don't think it matters.

ok done, heres new logs: https://gist.github.com/btd6player27/64804a0343c543161f8ee9b7b53e19eb

Could you try removing UnionLib from your mods list?

everythings working now. thats strange, i couldve sworn i needed unionlib for something else. guess not

let me just see if i can get into both dimensions

I need a full client log here, since this may be caused by a conflict with another mod I know of.

everything is working, only one small thing, the aether portals are weird. I can never take the same one twice it just keeps making duplicate portals all over the place

Likely an issue with a performance mod such as BadOptimizations, you'd have to check the mods for a conflict.

Interesting, report it to their issue tracker so they know to look into it: https://github.com/CaffeineMC/lithium-fabric/issues

it was lithium.... why does it do that ?
