I don't know if this has been covered before, and I'm fairly certain this has been happening for as long as I can remember actually, but still, whenever I travel back through the doors in Bottom Garden, returning from the area with the big mansion (where you can find the Music Box Creature), I go through these black doors that connect the red path that leads to that place (before the downward stairs). Ordinarily, as I travel to the left through them where the player was mainly intended, no problem, but going back from the left to the right through one of the black doors, strangely, I am ALWAYS greeted with a black screen.
It's easy to fix, however. You just go to your menu, and back, and the screen is back again. It's just a very minor inconvenience if anything, but I'm fairly certain it's a small glitch that might confuse other players. Just something I always wanted to bring up, and please let me know if you experience this as well coming back from Bottom Garden. Here are some screenshots that show where this happens...
See, I go in from here...
...Hey, who turned out the lights!?
I open and close the menu and...Ah, there we go! Through here I walk again...
