Datapack Error when Trying to Load a World

[SheltieChan]

The game loads, but when I try to enter a world it refuses to load because of a "Data-Pack Error".

I'm on Forge using Sinytra Connector and FFAPI, I'm not sure if there's any specific logs I could give you to help figure out what's happening.

A crash log was created despite the game not crashing, so here's that :

these are biome related errors - inventory tabs doesn't even touch biomes. do you have a minimal repro case?

It's just when I add it to my modpack and try to load a world, the worlds refuse to load due to a datapack error. I'm not sure how to give you a way to reproduce that short of literally making my modpack.

Without this mod, worlds load just fine, so I don't know why this would be creating biome errors at all.

you'll have to bisect - disable half of your mods and see if it fails, rinse repeat until you have the minimum number of mods required to trigger the error.

After a bunch of mind numbing toggle flipping, I FOUND THE MOD!!!!

For some reason, I have no idea why, Framed Blocks is the one that's causing an error with Inventory Tabs.
