Can't get any memory influenced map

I'm playing league and have finished the Eagon questline. After that, I met Eagon in the map again and activated the loneliness memory line of maps, finished the maps, and got an Echo of Loneliness item. I didn't play or sell it, just put it into my stash.
Then I'm stuck in my map drop. I've played more than 40 T16 maps, dropped 60 or more T16 maps, none of them are memory influenced, and no Eagon appears. I have no idea of this situation, if this is intended, if something is wrong with my understanding, or if I encountered a bug.

I don't think they are super common. I've got about 5, probably played about the same as you or a little bit more. I think it would be just off map drops and RNG. I'm dropping way more t17 at the moment than that. Probably 3 or 4x. The only other thing I could suggest is maybe rolling them your self or buying them if you want to run them. I don't think you are particularly missing out on anything. You've done the quest line, so you would know what they are like. Most likely RNG. I don't think there is anything that blocks it, I don't know for certain though.

I finally got one memory influenced after more than 70 maps, and then Eagon appeared in the next map. idk if there was sth fixed on the server side, or just my bad luck ended.
I'm not sure the accurate drop rate of that, or compare with t17, but before the memory line of maps, I can get about 5 in 50 map drops, so in my mind that's not that rare. And the quantity in my last 50 maps is about 20% higher than before (with chisel, to meet the nameless), so the situation seems abnormal to me.

Yeah i've gotten a few more and had him show up since last post as well. I guess the idea of them is for it to be a stepping stone between regular maps and t17. I found the bosses to be a bit underwhelming, but if that is their purpose it probably does help smooth out the progression. Having them build up from the alters does give them an interesting aspect.

The only thing I don't think is great is it feels like you need to do Eagon straight away, or else he might be blocking from spawning again. Which they have improved on a lot of other content, so you can do them when you want. Probably is an improvement on the memory system that felt a bit separate from the atlas before and required knowing which ones were worth doing. Maybe they will add some of those different types back later.
