I got this exception for array whenever I'm close (or even far away when chunk load is high) for different minecraft worlds. It is always the same coordinates, so something must be wrong with code that points to method "getSprite"

---- Minecraft Crash Report ----
// Surprise! Haha. Well, this is awkward.

Forgot about versions:

Minecraft java fabric 1.21.1
Continuity 3.0.0+1.21.1

I was able to reproduce this.

The issue is that at specifically that position, the random seed is equal to the smallest possible integer value (-2147483648). Computing the index uses Math.abs, which has this sentence in its documentation:

Note that if the argument is equal to the value of Integer.MIN_VALUE, the most negative representable int value, the result is that same value, which is negative.

This means the RandomIndexProvider$Unweighted returns a negative index.
