I'm currently using a generic controller for the game, and while it works fine when I'm running the regular game, it refuses to work with mods on. I've tried using inputmapper to change it to an Xbox360 controller, but my computer absolutely hated it, and it didn't work, anyway. Running on Windows 10, SMAPI 1.3.8.
Mods I have installed:
Stardew Valley Expanded + its required mods
Seasonal Cute Characters
It doesn't give me any sort of error, it just doesn't work.
