Error: Could not find specialization 'FS22_BourgaultPack_LF_NH3.componentPlacementFix' for vehicle type 'FS22_BourgaultPack_LF_NH3.extendedFertilizingSowingMachine'.
It's an old specialization that isn't needed any more, I made some changes a d forgot to check the log, I've already fixed it and re-uploaded it, so just re-download and it should get rid of that error
