Recently purchased the life and death expansion pack on ps4.
My sim had an outer body experience via the bog and turned into a hamster! Could not do any ghost mastery, and all outfits were the same, returned to normal the same way but could not raise ghost skills.
Also, after first trying the out of body experience action, for some reason my sim is frequently angry with the "this sim was angry in life and death" and this emotion repeats throughout the sim day, every day.
My sim is cheerful and does enough to dissipate that mood but I've only had the pack for maybe a week or 2 and these problems arose.
I've restarted and updated. Same issues.
