Hi, a few days ago i was going to go catch my raikou, i had 2 consecutive wins with the guardian boss, but when i battled him and won the raikou didn't spawn so i talked to the guardian to check my wins and he said i only had 1 win, the same thing happened with the other two guardians but the other normal bosses didn't seem to be affected by this problem. Was wondering if i did something wrong (i did have my zap bell) or if there was some sort of bug since the last bosses update. Thanks in advance.
