What happens:

adding a custom vein in the nether spawns the vein correctly, but places the sample on the nether roof

What should happen:

the sample should try to be placed on the first "surface" nether block that isn't the nether ceiling

Additional Comments:

Thanks

Fixed in 637e8fd :D

Yeah, the same issue occurs with Extra Utilities' Deep Dark. I'm not really sure what to do about it, I'm using Minecraft's base mechanics but they seem to return lazily-calculated values.

Maybe look for first available air block above sample?
