for SCM I have been defeated by her 9 times and caught her 4 times. So when the ghost hunt simultaneously I have also put the potion into the cauldron. so when the ghost appeared. What appeared was its original form. at that time Michiko and I rushed to hide but what happened was a shock to masuo and Michiko they came out of hiding and disappeared from the door and no one knows where else.
Tsunade i think not a bug. Because i reset in lady mystery and there are no problems with the questline
