After the most recent wipe, I test rolled a few toons to check recipes..
First Bubba, logged out, logged in, delete, new bubba
Then logged back out, logged in, Old Bubba and New Bubba were there...
Deleted Both and made a Joe...logged out, logged in, 2 Bubba's and a Joe...
Deleted all three and made a Tom...logged out, logged in...
2 Bubba's and a Joe...no Tom.
No way to delete the first three toons now
