Deadly tarantula specters not appearing in desecrate pool

they are special map only spectres you can get from the boss room of arachnid nest, they can be spectered fine, but their corpses do not appear when you cast desecrate, this is a huge problem if they end up dying since youd need to open an arachnid nest map to get corpses to resummon.
