Quick update: There are actually two changes that are going to take place in order to work on fixing your Achievements and titles, and they are not both happening in 2.2.1 unfortunately.
What is happening in Game Update 2.2.1 is a projected fix for your broken Achievements, post-transfer. The titles which are granted from Achievements are still planned to be fixed, but currently slated for 2.2.2.
If after 2.2.1 and subsequently 2.2.2 you have broken Achievements and/or titles please contact CS and they should be able to assist you further.
Um, Eric... my titles are back
Did you guys pull some overtime?
