I have a question about the time cards. I went into my local game today and saw they only had the 60 day time cards and I was wondering if they stacked, e.g. I bought 2 60 day ones so I would get 120 days and all the vet rewards? Or just the 60 rewards and 120 days or the 60 day rewards and some obscure time because I hold little trust in time cards atm?
