Do you use executable mods? Downgraders, engine fixes, etc? I'm also curious what mod manager you use, because getting MO2 to work under linux is a bit janky as well.

it's a question of tooling, modding kits

most times it this tooling which causes issues not the mod itself

For very popular games it's not rare if moddingkit/tooling producer (or contributes) made the tooling work on Linux, but it can be very hit or miss.

but it increasingly more "just works", kinda, somewhat
