They made an update and removed the "numChannels="6"" which was the problem so it should work fine now.
Anyway. I have all their swaths with my own textures and more, so for this map it is kind of useless.
About texture, is it me or the grass cut is a bit "flashy" ? The green is really intense compared to the grass itself
grass, clover and alfalfa fresh cut I think are a bit more saturated than it should be. If I have time, I might try color balance them to match the crop, but will see.
