When I shift click to open the GUI, it opens and then immediately after, my server gets a packet on the channel CJTECH and gets an EOF error.

It shouldnt be getting any packets though from opening the Gui should it?

I was just checking it was the right channel. Wow... I just checked. In my block i had some older packet code. Removed it, now things work. Thanks, I feel kinda dumb now lol.
