And same problem here.... 11 co-op quests completed and 6 regular quests, now nothing... Would have finished 14 co-ops by the time my 7 days are up on Saturday morning, and 8 by the time that my 7 days are up on Sunday am. Sure would hate to have spent the time to get skunked this week!
Post-script--just finished my 12th co-op quest, and am still showing zero done. Ditto none shown for regular quests. A fix before Saturday morning would be great!
