Interaction with Wisps seems to be broken ?

Hello.

I was giving Wisps a try again this league and I noticed quite a few things.
Long Story short the more Abyss Pits you have on a map, the more likely it is for wisps to get completely cancled out. Im not sure if this is intended or not, but i thought ill report on it. Everyone hates wisps and i give it a shot ever since they got introduced. And in Theory they should be quite good on for example double overrun abyss maps. But while trying that i instantly noticed that they dont spawn , the little symbol on the right is unticked , the whole map is cleared and there is no wisp symbol on the map.
