This might be just on my end somehow but after filling the bar to banish custom ghosts it gets stuck in the animation instead of allowing me to exit, forcing me have to leave the mission otherwise im stuck.
Make a backup of your StreamingAssets folder if you have any translations done then delete everything in the game folder. Redownload the game and try again. If the problem still exist post a video if possible using mediafire or anything else.
I thought it was because the climax code was missing a few voicetype but that's not the case. Thought it was because you have set language to spoilerish but it was worked me even though it was saying Mrs.K for all ghosts.
