I have some bug reports, played on 2.2.0:
Tips always show on death, regardless how it's set in the options.
If Spaniel comes in the back door, it uses Dead-Pea's end screen and tips.
Plush-Mate's poster sometimes gets stuck on the "..." stage.
Beating Hard Mode in free-play before unlocking the extra characters led to a black screen softlock after the 9:00 cutscene.
Pausing and unpausing in hard mode causes the music to play twice at once.
The fade-out for exiting the Extras menu takes twice as long as other menus.
The doll and 'watch me' characters won't unlock in the extras menu, their bios or jumpscare.
"Use the Left and Right arrow keys to switch up characters" shows up when you open the extras menu, rather than when you look at the character bios, and has an extra space before "characters".
The jumpscares menu says left/right mouse button, instead of just left.
Not sure it's a bug , but I can't figure out the true ending. I got up to a silver star by playing normal mode, but nothing happens by beating it again. Beating hard mode in free-mode doesn't seem to do anything either, but it takes you to the main menu instead of the free-mode options like normal.
I didn't find any accessories either, but the only thing I did other than 'start the night' and hard mode was 1 randomized night.
