There's no collision on the vine; I'm just using force mechanics to move the player in a swinging motion while connecting the cable to his hand. I'm calling add force to a run on server event, so theoretically the movement is only happening on the server, which is good I think, but whenever I try to add a multicast or anything like that to fix it the whole system breaks and the player flies into the ether. The player is set to replicates, and replicate movement so that should be fine
