using the Modpack Manufactio running on a homebrew server (Config , library , scripts , mods - journeymap copied to server running forge 1.12.2-14.23.5.2847 ) i get this error spamming my console when there's a Military Incursions trying to spawn one specific entity. (also the attackhelicopter in question doesn't spawn at all.)
