I have the same problem:
my uefn map had XP before the patch.
The email says it grants XP. After the patch there was no more XP, but a new email that also confirmed that the map grants XP.
But it doesn’t!
My other 1.0 creative map has the same problem: it granted XP before the patch and after the patch until about 02:00 am (Europe). The email said it is being calibrated. Today I made an update for the 1.0 Map and for over 5 hours still no XP.
Please fix this quickly. Thank you!
These maps are affected: UEFN-Map: 9544-9984-9560 and 1.0-Map: 5049-6507-5084
