Oh oh, you have the old nested folder problem again and the software cannot read the food items in the nested folders used in Martin's outings. When you see the line with food\food\food.def that can only mean one thing, a nested folder within the RWFF food folder.
https://www.carcoverworld.com/ Open your food folder and find all the unopened folders within it, expand the unopened folder and copy all the food items right into the rwff food main folder and then delete the empty folder. When asked permission to overwrite, just click yes to all.
