Eater of Worlds altar challenge doesn't work

In the "Use eldritch altars", one says "Defeat a T16 map boss in a rare map, with 4 eater of worlds altars affecting the boss, with Eldritch Gaze allocated"

I ran a Cemetery T16 Rare corrupted, took exactly 4 altars giving the boss buffs, killed the boss afterwards, no completion.





Could it be a bug related to the one causing the Searing Exarch altars challenge to not consider the right altars ?

Also, I've noticed since the last update that VERY few eater of worlds altars spawns in my maps, which are all T16 rare with at least 90%+ quantity, and I took pretty much all atlas tree nodes related to it (and it didn't changed since before the update). I barely get one or two per map, even in the most juiced ones. I just managed to get 4 in that Cemetery map, but unfortunetaly, the challenge didn't work...

It's definitely a problem caused by the bug with searing exarch altars, because I was running Searing Exarch on my map, and I got the eater of worlds achievement...
