SSF no memory threads

Made 200maps+ no memory threads have been seen even with atlas extra points?

I'm on 100+ maps without any memory tear. All of a sudden they stopped appearing.

I have the same problem. They stopped appearing a few days ago and not a single one since then. I can't progress with my challenges.

I am not in SSF though, this is in trade league. So frustrating.

UPDATE: As suggested in another post, I tried running a T16 White map without any influence on the map device and it worked. Looks like a conflict with certain Atlas passives or influence.
