vein generation issue with "type":"curve"

[h4ilst0rm]

There appears to be an issue with the curve type as seen in the image. Some of the generated veins are about 3 times as long as the others, and are perfectly aligned in either cardinal direction. The smaller veins I get do curve a bit and look fine to me, but these 3x as long as configured veins do not seem right.

The image was taken on a superflat world using this added to the default veins json:

"redstone_curve": {
   "type": "curve",
   "ore": "minecraft:redstone_ore",
   "stone": "minecraft:air",
   "rarity": 130,
   "min_y": 20,
   "max_y": 80,
   "density": 100,
   "horizontal_size": 32
}

I am having the same bug in 1.12.2 with mod version 2.0.12.

Using superflat and generating in the air is a good debugging tip btw.
