Mods getting duplicated

I really don’t know how to explain it properly but i’ll try.

Basically whenever i update the resource folder to join a friend server the whole resource folder gets duplicated, Currently in the resource folder i got 57 mods, Now when i launched just normal BeamNG they have all been duplicated & now i got 110 mods installed.

I am very confused. Any ideas why this is happening? I’m really not interested in copying the mods folder back & fourth(?) anytime i want to do MP stuff and SP stuff.
