When you try to open the chemical terminal on a dedicated server, nothing happens and it sends an error to the console of the server.

I've tried to import a chemical (Fissile Fuel from Mekanism) into the ME System, but that doesn't seem to work either.

However, there aren't any problems in singleplayer. The menu opens without any problems and the chemicals are being shown and imported.
