Fixed particle rendering crash on MC 1.21+ The ChestEffectsTask was calling world.spawnParticle() with offset/extra parameters that MC 1.21+ no longer accepts for certain particle types without explicit ParticleData. This caused the beacon beam effect to throw IllegalArgumentException: missing required data class java.lang.Float every tick.

What changed: Simplified END_ROD particle spawning to use single-parameter method

Removed problematic offset/extra float parameters that require ParticleData in 1.21+ Beacon beam effect now renders correctly without console spam Technical details:

// Before (broken in 1.21+): world.spawnParticle(Particle.END_ROD, x, y, z, 1, 0.1, 0.0, 0.1, 0.0f);

// After (works everywhere): world.spawnParticle(Particle.END_ROD, x, y, z, 1);

Affected versions: MC 1.21 - 1.21.4 Recommended for all Paper/Purpur 1.21+ users experiencing console warnings
