Level 20 Unattainable
Don't know if this has happened to anyone else but on Nov 13, 2012 (after Update 16) when my fvs gained enough xp to make level 20, I was reduced back to the previous base level. I was level 18 at the time and holding level 19 (in order to continue with some lower level quests) but when I attained enough xp for level 20, I was reduced to the base level 18 in experience. That's TWO levels being wiped out!!! I filed an in-game report but GM said they can't do anything about it and file a bug report instead. No response yet.
Did you try going to the training NPC and trying to level up anyway? It might be a visual bug because of the way XP resets for epic levels.
You're a genius, that worked !!! Even though the character panel displayed level 18, I was able to go to the training NPC and make level 20 without problem. Thank you for your help :]
