OK, I've played a hero to 50 and a villain to 30 so far, and I'm definitely sure now that some contacts who are supposed to introduce themselves are not doing so.
For example, Keith Nance & Jenni Adair on blueside, Dean MacArthur & Leonard, Vincent Ross, and Dean Yu on redside. among others. Also, whoever gives the arc about the rogue police and the mediporter technology on blueside.
Note I don't mean the ones with special prerequisites to unlock, like Veluta Lunata; just the normal level-based unlocks.
I know these arcs can be accessed via Ouro, but it would be nice if the contacts appeared when they are supposed to in normal play.
Anyone else having this problem?
