Me and my buddy (on Switch btw) have just started farming to try and do some of the new content and we decided to get him his Sister first. Once he Mercy killed his initiate and got his Sister we went back to the Exterminate on Pluto to get myself one and after completing at least Rank 1 of Zenith Crown voids we couldn't get anything to spawn. I dont know if it is bad luck, a bug, or if it is set to where if someone in the party already has one that you can't spawn anymore for the whole party. I know I could get Kuva Larvalings when my friend has an active Lich so I really want to get an answer to this if anyone has one.

Edit: The graphic you get after clearing the Granum Void that shows you your kills, time, and rank you got is also not showing up for either of us now.
