I hate to say it but try a new save as your video showed they were mown prior to the crop fix which required a change to the actual crop. Sorry again if it forces a restart
I say this as i Have two Beta Testers and my self trying to duplicate this atm and none of us can get the black texture
I have one more patch coming within the next 24 hours as i found a bug reported on a poached 3rd party site i need to address (not pertaining to this) This As of now will only effect the Homestead edition as there is an issue with the Sawmill on that version.
