I have no clue what causes this but for some reason whenever I place xml modded interceptors (0.25x scaled) on my aircraft the game may crash randomly crash and when I come back I see that my interceptors have now become guardians. They keep the scale and work fine they're just guardians now. I haven't been able to find any definitive cause as the game will crash randomly and rarely. I have noted that the game will no longer crash with the guardians on.
Oh yeah: I'm running the latest version on iOS.
