There is always a solution to still make it work, despite the path checking. But good UX is generally about making things simple, resilient (can adapt to a variety of users with a variety of technical level), and not add unnecessary complexity. Why do you think we should keep the path checking? What is it useful for? Note that in the examples I give, I pretend like files after the folder where is the mod.json matters but actually it doesn't, yet anyways..   Community mod was downloaded probably exclusively on mod.io I think. As for Feldmap, it is marked "compatible" for convenience although it's obviously technically incompatible.   Can't agree more.
