So, I discovered vault 81 randomly during my adventures in the commonwealth, and when I got in, I used my Charisma to persuade the Overseer to let me in without giving her 3 fusion cores. After talking to her, I proceeded to the right, past the radiation things but the Door says [INACCESSIBLE] and no matter what I do, I cant open it to get in. This NEEDS to be fixed, because there is a bobblehead in that place that I want so I can get the platinum trophy. Please Bethesda, look into this.
