Steps to Reproduce

Add any new ore veins that uses the layeredVeinGenerator and only has one layer. If there are two layers the issue goes away. Add the following scrip:

GTCEuServerEvents.oreVeins(event => {
  event.add('kubejs:test_vein', vein => {
    vein.weight(40);
    vein.clusterSize(20);
    vein.density(0.65);
    vein.layer('deepslate');
    vein.heightRangeUniform(10, 50);
    vein.layeredVeinGenerator(gen => gen.buildLayerPattern(pattern => {
      pattern.layer(l => l.weight(1).mat(GTMaterials.Cassiterite).size(1, 1));
    }));
    vein.surfaceIndicatorGenerator(
        indicator => indicator.surfaceRock(GTMaterials.Cassiterite)
                          .placement('above')
                          .density(0.4)
                          .radius(5));
  });
});
