[Standard] Zana Abyss bugged- no abyss on Carcass

I paid 5c, it shows that it applied the Zana mod on the map description on the right, however no abyss in sight. I made sure to fully discover the map, thinking maybe I ran it over by accident. 0 monsters remain, 1 elreon. It was not in the boss room either.

Same thing happening on t14 shaped moon temple, don't know if it also happens in unshaped moon temple, also made a Bug report, also didn't get an answer just yet. I'm in league tho
