Ok, This makes no sence whatsoever. There are TWO PAGES of the same item, the life Crystal, exept the other ohe says Heart Crystal.

They are the same thing. The same thing. 

Yeah the other one is the "item in your inventory" and the other the thing you break, but I think it's safe to assume they would not name them via different name. "Heart Crystal" never appears in the game, "life crystal" does.

So yeah, maybe someone capable could fix this( not me)

Edit: Welp, never actually noticed it's called heart crystal on the minimap. It's still odd, and has happened before
