When I've deployed Adlo+Eye and nothing happens until about 5 seconds left before it falls off... :|

Could it be you haven't completed the MSQ quest, "Before the Dawn"?

Ooh, something similar happened to me with that NPC!
Did you accept leves in Limsa Lominsa for that area? It kept telling me to report to Ourawann after completion but I hadn't accepted any leves...

Oops, okay, so managed to figure it out by returning to Limsa Lominsa after another attempt at abandoning one of the quests, which was successful. Had to collect my reward from T'mokkri since that's...

I don't have any ongoing quests as they're marked green? (aside from 1 story related)
Ourawann doesn't have the green mark either
Ah, I'll post screen shots when I get home (;´д｀)
