The situation is simple – I completed all World 1 zones in Tribulation mode, earned King Toad coins, turned them into a weapon in Mystic Forge and then, when I was searching for nearly completed achievements I realized that Glutton for Punishment (for those who didn’t remember this one – it is obtained for completing all zones in World 1 in Tribulation mode) is still uncompleted with 2/3 rather than 3/3 and marked as completed.
Any suggestions what is wrong?
