Since I recently leveled up to 32, I've been seeing players use weapons with 17 combat stars that shouldn't have that many, mainly the adamant bomber and minigun shotgun, neither of which can go up to 17 combat stars, it would be a similar case as to the anime scythe in the shop is 15 combat stars even though it only goes up to 12, but the adamant bomber remains at 15 combat stars where it was before I level up to 32, does anybody know why this is
