Meridian did something with craft manufacturing, I think he needs to have a look at his code Conqueror is unique in the sense it is produced by: producedItems: command.
Technically not my code... the problem is in the manufacturing profitability calculation.
It cannot handle a situation when a craft (STR_AVENGER) and an item (STR_FUEL_CAPSULE) are produced at the same time... which I can fully understand, because it makes totally no sense.
I fixed this particular situation (when producing a craft produces also items by accident)...
...it will still fail in situation when producing an item produces also a craft by accident :-) I hope you don't have such things in the ruleset.
I still recommend splitting the manufacturing into two, one for avenger, one for fuel capsules.
PS: wtf are the pre-requisites?? 2500 alloys, 2500 elerium (that's 100 landed missions!!!!), and a lot of other stuff... when the time comes, I will just cheat it in... no way I am playing milk-runs for 6+ real-life months just to get that stuff and bore my viewers to death.
