i also tried adding Connector Extras after i read that it helps with translating terrablender, and the modpack has terrablender installed but that didn't help

Downgrade Sinytra Connector to 2.0.0-beta.10+1.21.1 and it should work.

ZANXEY This is correct. Basically all Sinytra Connector versions for 1.21.1 since beta.11 are broken. I was hoping they'd fix that at some point, but even the beta.14 version that was used here still crashes in the same way.

ChatGPT wasn't entirely wrong here, "Connector didn't remap it correctly" is indeed what happened. But this is a bug since Connector version beta.11 rather than a limitation. Older Connector versions can remap that just fine.
