I've done at least three quests, but the counter (both in the side and on Pete's page) says I've only done one quest.

Haven't seen a report for this yet. Has anyone else noticed this? Is it messing with Alexander's latest quest?

Same here. I did 1 quest, and it's not counted. Also, there was an error like yesterday after finishing the quest.

Are you still having trouble with this?

I did a few more quests sometime later, and they were starting to count normally again. Just tried a couple now, and it's still counting correctly.

Don't know about anyone else, but it's working normally for me now.

I had a similar error: I was doing Quentin's quest when the counter (was at 22) was reset. Now I have only 2 quests done in the counter.

Nope. The first quest got counted, even though it didn't show on the counter.

Locking this as resolved. :)
