Seems like the 0.05B_E public version still has the issue with not being able to purchase the required amount of cards to leave the deck screen.
Can you walk me through what you're doing because in my testing, I can't not get it to work. Are you on 0.05B_e? Did you skip the intro or play the intro? The game tasks you to buy 4 of the Bronze I packs which is the $300 one and no matter how many times I tested, I can always buy more than one so I'm having trouble figuring out where the bug is.
Late reply sorry, tbh I don't really know how to recreate it. It just happens, for me it happened when I skipped the intro as well as going through the whole thing. It says I have enough money to buy the pack but wont let me. It's just greyed out as if I don't have enough. I'll be testing it again to see though with a fresh download.
