Memory tears not spawning in maps ( after the patch ? )

I realize this could be complete dumb luck, but after doing hours and hours of t16 maps, juiced or not, and not finding one single memory tear.... did ONE T13 map and got one right away. After I completed the chain. Did one T13 map and one T14 map and got another......

just found one after 176 maps, working as intended?
(t16.5)

Hi, I was also stuck here for about 100 maps:

Originator Memory Influenced Maps (50/50)
Courtyard of Wasting (4/4)
Chambers of Impurity (3/4)
Theater of Lies (2/4)

After reading several comments, some seemed to say that removing the influence worked for them, and others that they should have removed the mercenary.

Honestly, I don't know if it's due to chance or something, but I managed to get one.

I removed the influence,

1 map -> nothing

So I then removed my mercenary (and the influence as well).

1st map -> nothing
2nd map -> Memory Tears

Try it, tell me if it's really just a coincidence.
