I am having several issues with making this mod work.
1. Using a Gamma AI Core, I have analyzed a Ballista Missile Launcher. According to the order production screen, it should cost 8 Metals and 4 Fuel. I have 200 metals in storage along with 100 fuel. I have the same in my inventory. In the trade menu, there are 20 of the missile launchers listed. They are however red, and say insufficient resources. I am unable to order them.
2. Hitting the leave button from the main menu does not undock from the station. It appears to have no effect. You can hit escape to undock from the station.
3. The only way to leave the "Order from *" dialogs is to hit escape which undocks you from the station rather than returning to the previous menu.
I have tested this with all of my mods installed, as well as with just Omnifactory, Lazylib, and Graphicslib.
This is against the 2.2.0 version of the mod.
