Did you guys tried a custom script?
Go to Plugin Editor, create new, and inside the PluginRun function add this:
Code:
SetPlantMotionType(PlantMotionType.Standart);
SetPlantAlgoritm(PlantAlgoritm.MaxPerfomance);
PlantItemsAtFarm("Multi-Purpose Aging Larder", FARMID); // Put the name of the object exactly how it is in-game, and get the FARMID from the scarecrow plugin.
Btw, even with the MaxPerformance set up, you AB can still screw a bit the placement.
