Eagon / Memory Threads

Is there possibly some kind of bug ongoing with Aegon and memory threads spawning in maps? I've done 300+ maps since I last saw Aegon spawn with a memory thread, didn't transfer character since I saw that was hotfixed.

Been doing regular juiced and semi juiced maps and was getting memory threads in like ~20 maps inbetween max, sometimes just a handful, then I few days ago I noticed I wasn't getting any memories, even if I played for a few hours a day, respecced atlas tree to have a higher chance to get memory threads (didn't take any notable with the -% for X) and still haven't seen any show up.
