i just opened my vault and got crap as usual, so i chose to take the 2 tokens in exchange.
first i had to sell the 11 i had from season 3; no big deal; i got 11k gold. went back to claim my reward from the vault- it still gave the greyed out season 3 tokens. i threw them in my bank bags because i’m set to auto vendor greys and had to buy back the 2 “new” ones.
