In the red crystal caves area, I had a chaos/white crystal heart spawn and upon breaking it, had a Coast area spawn within the level. My guess is that it turned some of the walls into "water" tiles, but the game didn't handle it very well and when I stepped into it, I completely softlocked. Character turned invisible, was unable to die, shoot, use power, or move. The timer bottom right stopped tracking time, which makes me think it handled it as a "level transition" as if I had went through a portal.
