No Abyss in Mausoleum map

Found it odd that I ran 10 Mausoleum maps with Stream of Consciousness and all the abyss encounter nodes and didn't find a single abyss. I unspecced out of SoC and used an abyss scarab on my next Mausoleum map. The scarab was consumed, and the map says "Area contains an additional Abyss", but there was no abyss.

Bug report reference number: 3,756,772,180

confirmed.
i tried scarab sextant and even map device with 7 gate
nothing can spawn abbys on that map sadly..

Same happens in Crimson Temple map

Currently known, Crimson Temple, Mausoleum, Reef, Strand, Phantasmagoria. These maps do not spawn abysses.

Please let us know if you know more so we dont waste scarabs.
