Why does when I connect multiplayers install mods to 3 folders

I’m host, I copy my mods to server folder, resource and client. Then I tried to connect it, it move to the bin folder all my mods and then install it in mods/multiplayer of current version, mods/multiplayer of the latest version folder and on roaming/beammp/resources?

oh, latest it’s just 0.32, but why does it install in two derectories

That’s just the way the game functions, it uses file redundancies for checks and balances.
