Added New Game Plus feature.

Once you have launched your spaceship, open the mod options screen and select the XML file you want to load.
Then, when you start a New Game Plus scenario, you will be able to carry over the spaceship you launched.
Only Gravship spaceships can be carried over. If you want to carry over a regular vanilla spaceship, please use Save Our Ship Simplified.

After starting New Game Plus, unpause and check that no red errors appear.
Then save and load your data before continuing the game. The game will stop if you launch the Gravship immediately without saving and loading.
The recurrence rate should be fairly low, but if you get a red error about a duplicate ID when saving and loading, try starting New Game Plus again. Even if you load the same XML and start again, the error may or may not appear. Make sure that no errors appear before continuing the game.

Not all elements can be carried over.
Ideologies cannot be transferred. All pawns' ideologies will be the ideologies set at the start of the game.
Zones, workbench processing and other settings do not carry over.
An error will occur when transferring prisoners or slaves.
Item art cannot be transferred. They will be regenerated randomly.
Pawns in pods other than pressure-resistant hibernation capsules and in shuttles cannot be transferred.
If you inherit a Mechanoid, you may experience a loss of control due to insufficient bandwidth immediately after starting a New Game Plus. This can be resolved by removing the Mechanitor from its pressure-resistant hibernation capsule.
Special equipment, items, pawns, etc. derived from MODs may not be carried over. It is impossible to make it compatible with all MODs. I can make it compatible with MODs that I personally use, but I cannot add processing to make it compatible with MODs that I do not use.

Since the game has not been fully tested, we recommend saving the data just before launching the spaceship. If you encounter any problems, please post any error logs etc. in the New Game Plus thread.
