Anytime I enter the aether, I experience crazy lag. I can't open the lore book or any other item in my inventory. Trying to leave the aether via JourneyMap warp ends up crashing minecraft, and I have to close it via task manager.
I am playing a mod called Fantasy Skies. Here's a clip of what happens.

I dunno you're playing a massive modpack so I can't pin point it to anything here and I doubt it's Ancient Aether that's causing this

I'll also need more information like q spark report for example and also try if this accurs with just Ancient Aether and its dependencies, otherwise I'm closing this for now

got it. I'm very new to playing mods so forgive me if I come off as ignorant- I'll mess around with it and see if I can fix anything.

all good
