As shown in pet2 screenshot file, the dragon level rollback to lv5 instead of lv13 which it should be after feeding with 11 Dragon Marbles. pet4 screenshot file shown the Pet closeness has decreased for about 1100. What I did: 1. Purchase 11 Dragon Marbles from cash shop. 2. Open my pet and use all the dragon marbles. 3. Close my pet since it is distracting while I am having jump quest in kerning subway. 4. Open my pet again while waiting for my friend at the end of jump quest. 5. Pet level shown: level5 only. Add on: There are no commands to increase the closeness of Blue Dragon Pet too. I can't seems to find any words that can get the Dragon's feedback. IGN: OhMySL
