Hi! In the DamageNumberParticle

int index = CritMode.extractIntegerPart(dz);
this.xd = POSITIONS.get((index % POSITIONS.size()));

will fail if index is negative. FloorMod should do the trick here, e.g.

this.xd = POSITIONS.get(Math.floorMod(index, POSITIONS.size()));

Specifically this issue can happen if another mod or maybe commands spawns that particle (In my case a particle previewer), passing unexpected velocities.
