It’s being fixed in the next update, and is mainly caused by issues with potions and certain playermodels, so switching those should fix it for now (Without using the ghost morph).
It’s just a temporary solution until the hotfix, like science bird said. It’s just faster for me to equip the ghost morph than to switch my playermodel
In case it wasn’t clear, I was talking more about getting the ghost morph, not just equipping it. But I understand that this is a good fix for those that have this.
