Issue
Any entity of the type "burner-generator" shows up as an electricity consumer as well as producer. This was tested with primary and secondary priority output. Mods tested were an indev mod attached below as well as AAI Industry [0.5.22].Below are two images depicting the issue. One with fuel in the entities, one without fuel in either entity. Note, the engine item icon is the temporary icon for the burner-generator for my mod.
