When you merge a spirit with other identical spirits it gains bonus stats (blue numbers). However if the spirit in question has reached it's maximum level, i.e SR: 65  R: 50, etc. you can no longer merge into that spirit and it is stuck with whatever bonus stats it has gained and cannot recieve anymore. With this update the restriction is removed and you can merge into your spirit regarless of whether it has reached it's maximun level or not and gain the bonus stats.
