Homebrew Homebrew game Homebrew game randomly crashing

[BlyZe]

Fixed: I made a simple but stupid underflow error with size_t

size_t secondLastCactusIndex = lastCactusIndex - 1; //lastCactusIndex is size_t as well
if (secondLastCactusIndex < 0) secondLastCactusIndex = length - 1; //Yeah unsigned int < 0 **crying**

That's the simple fix

size_t secondLastCactusIndex = lastCactusIndex;
if (secondLastCactusIndex == 0) secondLastCactusIndex = length - 1;

I'm currently working on a homebrew game using libctru and citro2D.
When I play the game everything works fine but after a short time the game randomly crashes.
This issue didn't appear before I added the bird as new obstacle.

I would really appreciate if someone could help me there I have really no idea wtf is happening
