2k mods spent 4 hrs going through them all it only occurred with this one installed even happened with just this installed and nothing else im assuming its a conflict with something in the straw harvest that was just released because i didnt have problem till that
I thought it was very strange too until I saw the fillType errors another user sent me and I got it to happen in my end.
Normally when you have a fillType error, the production that is missing its fillTypes just wont work. In this case, if Swathing+ is unable to load its custom fillTypes (used for rice and sorghum swathing), when my script goes to make the modifications to the fruitTypeConverter (that is what tells the game "if you see sorghum, make it sorghum swath") it trips an error and breaks ALL of the fruit type converters. Without a converter loaded to the map, the game thinks the header and harvester are not compatible (a header needs to have the FORAGEHARVESTER converter to be attachable). Side consequence, this was also breaking mowers (mowing uses a converter to go from grass crop to grass_windrow).
