I have already submitted a bug report in game, but hasn’t seemed to help.
As should hopefully be evident by the screenshot I have the items that are the rewards for completing each zone in world 1 in tribulation mode. However, I am lacking the achievement for doing so.
On a possibly related note I can’t access world 2 tribulation mode either, whether this is connected to not having the achievement for world 1 is somewhat unclear.
Pure madness!
