i have built sorting machines and used filters with the trans port pies before but here recently my filters are just spitting out blocks when i apply power ( yes they are facing the right way and such ) . It acts as if my pipes aren't even there but i can clearly see they are connected also i cant build my sorting machine because i cant paint any of my pipes. i have tried to delete and start over but that does not work either. also where did technic go in the launcher?
