Hi Jinkou, before all thanks for your mods i play since FS22 (and some I transformed for FS25 for myself before your come back ;) ).
On this map, I just saw that "BUCKWHEAT_CUT" when using a combine mower became ....
Potatoes :D
Had a short look in the fruit types, fill types files to see if the mistake was in the "converter" but I saw nothing about patatoes so the problem is certainly deeper. I didn't try other crop yet so no idea if it happen with something else.
Edit: another small thing in your i3D:
<File fileId="590" filename="../multifruit/foliage//barley.xml"/>
the double slash makes the game unhappy. And you probably already saw the " Failed to open xml file '../../../FS25_Riverbend_Springs_Multifruit/multifruit/placeables/productionPoints/fermentingTower/fermentingTower.xml'." because of the case sensitive from the "FermentingTower"
