Minecraft: 1.20.1

The newest versions of Simply Skills cause great performance decrease, lag, and greater chance for disconnect (single player), the versions previous to the Spell engine changes did not have this impact on game performance, and it only happens when Simply skills itself is present. Pufferfish and the dependencies don't cause the issue.

and a strange thing, opening the Skills screen can freeze the game for a few seconds, even a minute

I will send a log soon, on cellphone rn-

I can't see any issues pertaining to Simply Skills in the log, and you'd be the first to report any performance issues.
Are you perhaps able to profile the server with Spark while this performance issue is present?

In regards to the skill tree hanging when opened, you may want to double check your keybinds to ensure that it isn't conflicting with your shaders mod. There's a good chance you're unloading & reloading shaders, as I believe Iris has a keybind conflict with Pufferfish Skills by default.

I don't have shaders or iris, maybe puffish's keybind changed in newer versions? or one of the spell engine dependent mods is causing conflict with the key
I'll see what I can do with Spark

Hy again! I finally finished updating my mod list, can get around to finding out this issue, but Idk exactly what I'm supposed to do with spark, I play on single-player only

also, this is just a rude guess, but maybe the new animation for the background (Space and spinning planets) is heavy? I still get the Freezing from opening the Skill menu
