Memory Threads completely stopped appearing in maps

After completing Eagon's questline, memory lines never appear.
I have run maybe 500 maps since without a single one and I even have one of my atlas trees set up to make them more likely.
I have tried running them white without any scarabs after someone suggested they were being blocked by other content, but still nothing.

Same issue,

I've tried blocking everything on the atlas map. Haven't seen a memory spawn for hundreds of maps.

I found a tear while levelling an alt in a t7 map, after finishing the quest line. Which I dont think should be possible.

It's the most fun i've had in Poe in years and not being able to play the mechanic is really frustrating.

Bump. Still broken for weeks. Either fix or turn off it's challenge.

Second this

Same problem here, i reported it in the other thread also..

Been running destructive play for now 3 days, which is 100s of maps and i have not seen a single tear.

I have gotten 1 tear since finishing the league questline in an alc and go map for sulfite so it might be some weird interaction like abyssal depths where you have to take the whole abyss snake for them to spawn despite having the 100% increased chance nodes.

I do have all the league nodes on top of the atlas tree except the 80% chance to NOT encounter one of the bosses as i need all 3 for the challenge, but at present i am about to give up and just quit league altogether as no progress on challenges due to a dumb development decision to make a challenge that is dependant on 100% rng, or whatever else is going on..

Please GGG fix this asap
