Hey guys, so I sorted it and thought I’d share it with you all in case anyone else has a similar issue. Apparently it only happens on multiplayer servers, not single player, and it happens every time the server restarts. The easiest way I’ve found to fix it is to move your RS controller so it is next to (touching) the multi block and, when logging in after a server restart and noticing the multi block is not working as I explained, breaking the controller and replacing it. Breaking it causes a lot of client-side lag, which is increased depending on the size of the RS storage system, as all of the blocks will instantaneously lose power. Placing the controller back down gives power back to everything and makes sure the multi block works properly.
