Did you see the bunch of warnings in the log about your fruits ? For each you have:
Warning(../FS25_Riverbend_Springs_Multifruit/multifruit/foliage/onion.xml): FruitTypeDesc.loadFromFoliageXMLFile: Missing fillType 'onion' for fruitType definition. Ignoring fruitType!
Warning (../FS25_Riverbend_Springs_Multifruit/multifruit/fruitTypes.xml): FruitTypeManager.loadFruitTypes: FruitType 'ONION' referenced in fruitTypeCategory 'PLANTER_SMALL' is not defined!
Error (../FS25_Riverbend_Springs_Multifruit/multifruit/densityMapHeightTypes.xml): 'map.densityMapHeightTypes.densityMapHeightType(32)' has invalid fill type 'ONION'!
Looks like a path trouble or something missing somewhere .
