Sorry I don't understand the quote but I have the same issue with 1.19.4. But I have multiple times this error (1 for each vertical slide bloc) : [19:03:10] [main/ERROR] [minecraft/LootTables]: Couldn't parse loot table supplementaries:block/blackstone_tile_vertical_slab java.lang.IllegalArgumentException: Can't find block supplementaries:blackstone_tile_vertical_slab at net.minecraft.world.level.storage.loot.predicates.LootItemBlockStatePropertyCondition$Serializer.m_81802_(LootItemBlockStatePropertyCondition.java:79) ~[server-1.19.4-20230314.122934-srg.jar%23181!/:?] {re:classloading} at java.util.Optional.orElseThrow(Optional.java:403) ~[?:?] {re:mixin} at net.minecraft.world.level.storage.loot.predicates.LootItemBlockStatePropertyCondition$Serializer.m_7561_(LootItemBlockStatePropertyCondition.java:79) ~[server-1.19.4-20230314.122934-srg.jar%23181!/:?] {re:classloading} at net.minecraft.world.level.storage.loot.predicates.LootItemBlockStatePropertyCondition$Serializer.m_7561_(LootItemBlockStatePropertyCondition.java:68) ~[server-1.19.4-20230314.122934-srg.jar%23181!/:?] {re:classloading} at net.minecraft.world.level.storage.loot.GsonAdapterFactory$JsonAdapter.deserialize(GsonAdapterFactory.java:102) ~[server-1.19.4-20230314.122934-srg.jar%23181!/:?] {re:classloading}
