Crash on launch with Beta 4

[NomSTeh]

I am using 1.14.3 fabric.

Unrelated but related (Crashes on startup) We might have to abandon the idea of a 1.14.3 version until the Fabric API stops stomping on the mixin refmaps. (FabricMC/fabric#227)

Sorry NomSTeh, it's happening because another mod is likely hitting the ChunkRenderer before Arcane Magic gets to it. I'll have to go over your modlst, may take awhile.

Loaded all the list of mods,figure.. It's optifine/optifabric
Far as I know, we aren't in compliance yet with it, ?YET?

Raphy, you wanna stick this on a todo for sometime. It's the rebuildChunk mixin... Appears Opti is targeting the same call on it and stomping on A.M. (Materialisation had a similar issue recently, might be worth looking towards them for an easy detect/fix)
