Have you tried reloading the game and seeing if that fixes it? If you're having issues with Dolly's content you can use the wrench in the phone to debug it
You're in the event where you get taken to the hospital with Leslie, right? and then going to the left and interacting with the glowing circle, then talking to Sweeps? As I said if you already did the hospital stuff and Dolly's quest line is broken, the wrench/debug room should fix it but I'm unsure if that does anything with Sweeps. What happens when you talk with the girl at the front desk?
Okay so I found a way around it there was no circle but I reloaded the save before u get taken to the hospital and used the cogwheel to reset dollys quest then I left the hospital after it teleported me there then proceeded and it the worked as intended 😅 thank you for the quick reply tho love the game and al the hard work u have put into it 👍
