It wasn't a bug. I just had it so anyone can enter the area with the rainbow immediately [so they knew where it was.] I also didn't think to make a self-switch in the game to fix that so I apologize in advance.
I wish I found a good face graphic for a Papillon as well. In the Post-Game Jam release for this game, I had hopes to get one. I just struggled to find a good faceset for the type of dog I wanted for this game. ^^;
But I am glad you gave it a chance! Who were your favorite characters if I may ask? [Also thanks for the plugin suggestion for next time!]
