1.20.1 injection failure and crash

[HotelCalifornia]

I'm running a 1.20.1 forge instance with a number of mods, and when I try to start it up, it crashes with

Caused by: org.spongepowered.asm.mixin.injection.throwables.InjectionError: Critical injection failure: Constant modifier method getActualReachDistance(DLnet/minecraft/world/level/Level;Lnet/minecraft/world/entity/player/Player;)D in mixins.reach-entity-attributes.json:ItemMixin from mod reach_entity_attributes failed injection check, (0/4) succeeded. Scanned 1 target(s). Using refmap refmap.reach-entity-attributes.json

I believe that this is coming from version 2.4.0, which is required by MythicMetals. I'm not sure if there are any other mods that require this one. I'm flagging MythicMetals specifically here because disabling it reliably allows the instance to load.

My suspicions are that either

• using connector and ffapi breaks things, or
• there's another mod that requires a different version of reach-entity-attributes and the two are conflicting

I'm not sure if the latter is possible, even, but I've been banging my head against the internet and SpongePowered documentation trying to get a sense of what exactly the failed injection checks are and I've gotten nowhere, so here I am.

Here's the full mod list, if it helps
