Not sure how new this is, but I just noticed Call in Favours in the Flit is now an Opportunity Card rather than a storylet. It seems like the rewards have increased as well: I took the Urchins option and got 20 Scraps and 17 Stolen Correspondence in return for ~100 cp of the Connection. (55->53)
I expect it’s 120 cp alike the other contacts? Though this is nice to know, should be worth it to cash in those, then…
(Not least because the Urchin/Orient conflict card is a good nightmares reduction)
