[BUG 0.0.1.9c] ERROR!'s out when there is only one fuel mode. Stock pod patch only adds one mode (monoprop - because pods usually have monoprop if they have any fuel). This bug was temporarily fixed by added a second mode(it can be the same as the first so it appears like there only one fuel mode) in the patch (LFO).

mangled config caused this. added error checking in cfg.cs - thank you LGG for this code.
