Unknown entity property for entity_properties loot table condition causes server crash for default loot tables

      Description

      The bug

      Specifying an unknown entity property in the entity_properties loot table condition causes the server to crash if the affected loot tables replaces a default one. Minecraft (client) remains open but stays at the "Loading world" screen.

      This probably affects previous versions as well, but I have not tested those.

      Description: Exception in server tick loop
