Niko does not appear on the map when I put a sulphite scarab

Hello,

I have a problem since several hours, all the sulphite scarab that I place with my maps do not work. They are "consumed" with the map but Niko does not pop!
Even worse, I can select a map with a sulphite scarab + add "Area will contain masses of Voltaxic Sulphite, which Niko will extratc for you" on my map.
It still launches my map without giving me the error message!
Please help me, I play mainly in the mine so if there is no more Niko I admit that it bothers me a lot (and the fact of losing my scarab without having Niko bothers me even more...)

I specify that the talent "Fungal Remission" is not selected in my Atlas Tree.

Growing Hordes keystone?

Yes, i have Growing Hordes
My bad.... didn't read the keystone properly

Thank You !!!
