[1.8.9] Creating a Fake Client in Modder Support Posted March 21, 2016 I managed to solve my problems by myself. It took a week of many tests and crashes, but at least it was very informative. For the first question, my NetHandler wasn't being updated because it's manager was a client side manager. The server side manager it was connected to was stored in a private list in the NetworkSystem, so I got it using reflection, and used it for my NetHandler instead. For the second question, right now I'm just creating packets in NetHandlerPMPlayServer.update() and calling the correct method to handle the packet. I'm not sure if this will cause problems later, but for now it works.
