I just started a server using All the mods 10 modpack on Akliz Game server hosting

I have played with the Apotheosis mod before on All the mods 9 and it worked great,
However, this time,
-The only bosses that are spawning are specifically the uncommon ones (Green),
-The only gems I am finding are either cracked or chipped
-The only affix items I get from mob drops and chest are common, uncommon, and rare (Gray, Green, and blue)
-I have not once seen a epic or mythic affix

On the server hosting platform

We have quite a bit of progress already in the modpack, I am hoping to be able to find a way to fix it without affecting the current playthrough

I really like this mod and I want to get it to work, I've tried finding fixes, but, a lot of the forums I check out make no sense to me, I'm just a player so I don't understand a lot of this stuff so all the help is much appreciated

Apotheosis added World Tier system in 1.21. World Tier
You need to unlock higher World Tier to get items with higher rarity.

The log spam is a separate issue from everything else you reported.

Yeah, that's my bad, I figured since I'd been everywhere (Overworld, nether, end) that it must have been an issue: thats on me. Thank you ur the best
