Happened to me to. Mostly when you walk into something during the night.
Hi. I ran into the problem described above when I was standing behind the counter in Bonnie's room. After that, every time I enter the game, I have no tasks, time is running out, I can't interact with anything, and Bonnie has been standing at the counter from the very beginning. Is there a way to reset the save (in the registry or in Explorer)? I tried to find it, but I couldn't.
I'm on the first night. I restarted the game because when I went behind the counter in Bonnie's room to the liquor stations, the same bug occurred as Rayner135. After a couple of such reboots, I had the problem that I described above (the tasks disappeared, Bonnie is standing at the counter and I can’t interact with objects). Moreover, if I tried to enter the gallery, it was the night with the problems described above that started.
