Hey Jab, You may already be aware, but the most recent update (32.30) has updates that bust multiplayer when you install it. Obviously this is not unexpected, since the current version is for 32.27 and any modification to LuaManager$GlobalObject.class has the potential to cause breakage in these circumstances. I just figured I would try to be helpful by providing the stack traces I am receiving when I attempt to connect to my server: The first occurs as soon as the main menu loads: The second occurs when attempting to connect to the server: I can attempt to connect without ModelLoader and it doesn't throw any errors, but the server utilizes ORMtnMan's Real Guns Mod so it obviously disconnects at that point since the mod doesn't work without ModelLoader installed. I tried taking a look at the classes myself, considered running a diff and then realized it would probably be a lot of work to even get the environment in the correct place to rebuild a patched class with the ModelLoader changes. In any case, thanks for all your hard work and I hope this helps you get ModelLoader updated to the new release. Thanks!
