I got this error after I updated to the Halloween patch. reinstalling the game fixed it.

If you look at the Capsule Gacha Probability Disclosure for the mixed capsules, or their "full party" mixes, you'll notice that each rare has a win percentage of 0.02% to 0.03%. With 51 "rares" in the capsule (looking at the Halloween Witch Full Party), on average your chance if winning any rare per spin is roughly 1%. Compare that to a capsule for a specific set or weapon, the combined chance to win any rare is basically 10%. So quite literally, mixed capsules are 10x worse. Then you can look at a capsule like Jimi. Only one rare you can get, and I believe that was a 10% chance for 1 rare. (Can't look at it now since they updated the thread). That is why some capsules are more expensive to spin than others, because it will take fewer spins to win the "full set" based on those odds & the amount of rares. Also your odds of duplicates are lower when you spin a capsule with fewer rares, therefor -> price jump. For the most part the prices aren't bad, with the full party and mixed ones being the crowned exception. I'll never spin on them unless Masangsoft matches the overall chance to win a rare with all the other capsules. With a little math, the capsule isn't all too bad. My current gripe is that the sommelier sets are in 1 capsule for both colors. Higher chance of duplicates that way 😔
