This Harvest Mission Fix mod will fix an issue where harvesting missions cannot be completed on some maps. It will apply to all new contracts in single player or multiplayer.
For single player, there is an additional debug display that will track progress and help identify other problems with the harvest or the completion of the harvest mission. You can also check the completion of the mission by collecting and delivering the entire crop from the field with one keystroke! This action will be applied to the mission currently selected on the debug display.
