I made a modpack with BackSlots and it was working yesterday, today I think I added some more mods, and then BackSlots started causing a crash. I think I removed all the mods I added (I could be wrong though) but it's still crashing, so idk what's up.

Here is the crash:
crash-2021-12-23_17.46.28-client.txt

Locki mod is incompatible and causes the crash
It has to update its backslot mixin

Ah, so I was confused about that because I saw it was an issue with the mod "Locki" but it doesn't appear in my modlist, so I assumed I was reading the crash wrong.

Apparently it's embedded into Requiem.

I can not fix this due to Lokis incompatibility.
