Good morning everyone.
Overnight a fix has been applied that resolves some of the problems with the new character boost, namely the missing level up of characters (e.g. character left at level 1).
If your character was in such a situation after the boost, logging it now should complete the leveling up and correctly bring the toon to level 80 
As for other issues (e.g. some characters not having received reputation or currencies, missing evoker talents) investigation is still ongoing.
