Now I need some help, I got my pack working for single player, got it working on my server now too, and managed to be able to get my friend to connect.. However, when they connect, they basically lag out. They can't type, breaking blocks makes them dissappear for them and they get no drops, but for me mobs attack them etc that they don't actually see. I remember reading there were MCPC+ issues making servers crash when a second person joins, but that doesn't happen.. Nothing is shown as wrong by the server at all. Any suggestions? Also the server is 1.4.7 and I used the 1.4.7 server files from here.
Edit- After about 5 mins logged in you reconnect, teleport to where you were, and your text starts showing up.. and then every so often it does the almost disconnected thing again, but for a shorter period. If ram needs to be changed, the bat file has 'java -Xmx2G -XX:MaxPermSize=256m -jar server.jar' In it, and I don't know what would need to be changed to allocate more ram.
