Servers are most likely overloaded. In my case, second keg I opened was refunded, however i believe i kept 4 standard pick cards, no 100% sure. Also, people are reporting unusually low rates on Gold/Silver cards, since the premium weekend, so make your mind up in advance if you want a higher CHANCE of better cards, or certain animated cards (I Believe that the choice rare+ cards are always premium)
Could we get a response from CDPR on this?
Btw it's called Premium Keg weekend, but how long does it last? it's not weekend yet. This means if i keep my kegs and open them after the promotion is over i get regular cards?
