Couple of questions / minor bug report:
The abandoned venture has
which seems like it has an extra e on the end there. Doubt it'll mess anything up too much as I suspect the default for that is false, but thought you should know.
Additionally, the rar file has a LocationAPI.java and a DerelictShipEntityPlugin.java in the root directory. I'm not sure they do anything in the root directory and they seem to be identical to the vanilla versions from the starfarer.api anyway, so they probably shouldn't be there?
The mission_list.csv merges like most other csv files, so I think you only need to add the new mission name in particular.... Unless of course, you're doing it this way to get it to show up halfway through the normal missions in the list.
Speaking of the mission, you've got
// Mark player flagship as essential
//api.defeatOnShipLoss("HSS Steadfast");
In the MissionDefinition.java
Isn't that going to mean HSS Steadfast can explode all it likes, since it's commented out? I haven't tested this, so apologies if the flagship is automatically vital or something.
Couple of things in the mission description:
unprecidented - unprecedented, line 8
hypothetic - line 8, is actually a word despite what the spellchecker thinks, but reads weird there to me. Any reason not to go with just hypothetical?
"Exhausting every single avenue of attack physical and political to stop the treaty from being ratified." - Line 10, fragment. Consider revising? Eheh, sorry, MS Word flashbacks, but just changing the previous full stop to a comma should fix this.
line 12, similar, the sentence that starts with "Effectively doubling" should probably start "This effectively doubled". Personally I would also change to "without having to consider a proportionately massive increase in industrial power" as the end of that line.
Overall thanks for putting so much effort in to make all the extra bits, makes the ship embed nicely into the world!
