Maven t14+ not dropping

So I juiced my first maven T14+ a weee bit too much and lost the fight.

Following that I ran a bunch of maps, and finally, made sure I did all T14+ without void stones and get a witness.

Continued with completing maps and got the red guys voidstone doing that.

But still, no maven and no maven invite drop ... cannot select maven,because she has viewed all the maps already. Can only tick blue / red guy.

What am I doing wrong? Run more new T14+ with the voidstone?

You don't need to run maven withness maps to drop the invite. I did the 10-way once, switched to eldritch influence maps and have 50+ maven 10-way invitations in my stash..I've also stopped picking them up.

Just run whatever maps you want, they will drop.
