Why the hell is the performance cost showing zero?

You must be asking; "Why the hell are you whining about this?"
Well, it's because I can't tell whether the plane can run on my device or not. If this problem ever prevails, I'd be unintentionally crashing my game.

By the way, that 801 part count plane almost crashed my game. Cause apparently it was almost 6k performance cost according to the builder.
