If you read the notes it says that if you have completed that map already prior to the update you will not receive any further notifications to say you need to re-complete tyhe map. just log in to the map area and then activate the missing way points, it will bring you back to 100% for that area
Just logged on from work, spoke to Tixx in overflow and appear to be getting the same issue as lots of other people, no gifts, and didnt spot that there was a chest. Partner logged in spoke to tixx and got items from the chest without issue.
Therefore i see an apparent bug with tixx at this time
