Hey i have a small problem with how this mod works with Nexerelin.
The faction has a permanent alliance with the Hagemony which completely makes sense, but it also causes the Alliace to stay if one of even both of them have been destroyed, causing a very annoying phantom alliance to hang around and mess with all of the politics alliance stuff.
For example if both of them are destroyed but another faction had previously joined the alliance, it will now be permanently stuck in there and can not be removed, because you can't lower relationships between a living and dead faction. The only way to remove them from the alliance is to completely destroy the faction and then resurrect it, in which case there is a 90% chance they will instantly rejoin the greater hagemony ghost alliance again.
This all only really matters if you have something like commissioned crews installed where adding factions to your alliance really matters, but when you do it really sucks to deal with.
Complaint aside, this mod is awesome! I love the ship designs!
