A few days later I invited a friend to play LE and we partied until the Ezra's ledger. When I got there, I talked with the gambler NPC and he just completed the quest and dropped his unique amulet. This character just got to this town and suddenly the game recognizes the quest as finished? Is it a multiplayer bug? Somehow the game "took something" from my other "solo self found" character.
Also, it's not clear to me how the quest catch-up happens. He teleported to me (at Keeper's camp" as a level 1 character, what happens to his quest log from the first town?
For the first part, we'd have to dive into the logs to see what exactly happened, I can't really say based off the description, it may have been a bug, or it may have been a quest state catch-up (such as if the friend you joined was ready to turn in that quest). If you submitted an in-game bug report, we'd already have these logs to dive into.
For quest catch-up:
When you enter an area, if that area is further along in a quest line than you are, you will automatically have all main story quests up to that point completed, and be assigned the current quest state for that area.
So when your friend had a level 1 character, and teleported to you in Council Chambers, their quest log would have automatically updated to have their main quest match yours. Their main quests from the first town would be auto-completed (side-quests are not auto-completed).
