when will you expand the maximum number of coupons?
it is very inconvenient when there are a lot of capsules, but you will not open them, since you received all the weapons for coupons and received the maximum number of coupons (200 pieces), you open capsules and you do not receive coupons, there is also no way to pick up disassemble weapons (which are not needed)
