My old tag was eEncounter and I had almost a full year of stats on that account.
However I swapped the tag name with another account I had that had a few hours played on Destiny. This tag is "Species".
However, it will not refresh my current stats to Species. It still is showing Species OLD stats, which is only like 16 kills in PVP... lol
It IS showing my 3 characters stats, however, and it's also showing species OLD account character stats. So I have 4 guardians characters linked to this account if you look at my stats... However the total stats still show the old tags.
