[Note that this is a continued file with a "black room" bug]
As Wigfrid, on day 88 or so, I destroyed a bramble near the edge of the map (not touching the boundary) with a halberd and immediately got stuck in the insanity animation. I could not unequip (right click) items but I could move them around to other slots. I could not eat but I could rotate the camera. I Alt+F4'd and things were fine. I did not attempt to hit the same bramble again. Destroying other brambles did not cause this to happen. It may also be important to note that before reloading I had killed the Queen Mant (around day 80) and the sound bug happened, as well as the permanent insanity lines around the screen. Reloading fixed this as well.
Hit a bramble near the edge of the map with a halberd on the second or third day of second in-world Lush Season.
