What happened?

i have a modpack with around 200 mods, and before adding the ice and fire mod generating new worlds took like 5 minutes max. after adding the mod this seems to be a lot longer. i left my pc for 2 hours and the world was still only at around 26%.

(i had to use pastebin for the log because i couldnt fit it in there, the maximum is like 65k letters

Minecraft Version

20.1

Ice and Fire version

2.1.13

Citadel version

2.5.4

Relevant log output

Other Information

• I am using other mods besides Ice and Fire
• I have attached a log file from the session that I have experienced this issue

minecraft version is 20.1, i set it to 1.16 by accident

i tried fixing the problem by generating a world without ice and fire and adding it back after generating, but now i cant find or spawn any dragons, not with /summon or spawn eggs. other creatures work fine though
