Hello ranchers!
A small hot patch has just gone live that fixes an issue with invisible plants which could not be removed and the crop plot had to be demolished. The cause of this was saving and quitting the game with a plant that had died (due to the seed deteriorating), when loading, that plant was invisible.
If you have an invisible plant from before this patch, you will need to demolish and replant it unfortunately.
Happy Ranching!
EDIT: This has been temporarily removed due to an issue with multiplayer connections, we are currently looking into this.
