So after a small update to our modpack suddenly EMC value disappeared for half of vanilla items so I tried to investigate the issue and downloaded EE3 Helper to make assigning the values easier(it doesn't even work)... There is a command to run the DynEMC so I ran it. This is what the console told me: http://pastebin.com/JDbFADPz

yes the same problem was happening to me i made a report in #937

See issue #935
