+1 — still reproducing on the latest release, SFM 4.34.0 (NeoForge 1.21.1). Same error signature on every boot:

[Worker-Main-4/ERROR] [net.minecraft.world.level.storage.loot.LootDataType/]: Couldn't parse element ResourceKey[minecraft:root / minecraft:loot_table]:sfm:blocks/buffer - Unknown registry key in ResourceKey[minecraft:root / minecraft:item]: sfm:buffer

Filed a more detailed root-cause write-up (the buffer block + block entity are registered but no sfm:buffer BlockItem exists) in #583.
