So stupid question in Beat Saber. Trying to use custom songs in multiplayer, and have the MultiplayerExtensions.dll in this folder, but don't see anything. I think in the installation instructions it says to put it into the base plugins folder in the main directory, but whenever I do that, it just causes a black screen after the safety warning. Is the mod just not working right now, or am I being stupid and doing something wrong when placing it in the base folder?
