At first I thought this was just that I was trying to build $300,000 of ships with only $125,000 of production. Each month I'd pay out the money and, I figured, after about four months they'd all be finished, right? Wrong. Six months later not a single one had been finished.
In frustration I cancelled the order and instead tried to build a single $40,000 frigate. Again, $125,000 monthly production limit. At the end of the month I was indeed charged $40,000 for the frigate but it was still shown in the build queue and, upon returning, no frigate had been built.
Oddly enough, I can build weapons and fighters aplenty just fine. They get build in accordance to the queue and get tossed into my inventory no problem.
Here is my mod list, in case one of them is the culprit:
Archaen Order 1.3.4d
Boggled's Terraforming 3.0
Combat Analytics and Detailed Combat Results 4.5
Common Radar 2.5
Disassemble Reassemble v 1.6.9
ED Shipyard 1.9.9a
Grand Sector 0.2.1a
Interesting Portrait Packs 1.2
LazyLib 2.4e
MagicLib 0.24
Neutrino Corporation 1.85-RC4.1
Nexerelin 0.9.5h
Starship Legends 1.3.14
Tahlan Shipworks 0.3.13
ZZ GraphicsLib 1.4.1
Now I'm not sure, but my current guess is that Achaen Order might be causing the issue because it is the only one that I've added to that list in several months and this problem began only recently. However, I also remember that it did not start at the exact same time that I added it. This tells me that something might have happened in an update along the way to cause this issue.
Any clues or suggestions?
