NPC provider replenish turns off hydrogen engines on ships if they have functional batteries/reactors to save a bit of performance

- Configurable FreePort Upkeep which is required daily per FreePort
- If faction holding the FreePort license changes or is no longer exists, the FreePort is dismantled
- If Faction holding the FreePort license does not have required amount of SC in faction bank, the FreePort takes 1 damage (same as with successful FreePort siege)
- If FreePort has more than 50 damage points it gets dismantled

Fund Siege Preparation will show which faction they intend to attack so player can decide if he want's to fund it or not. This makes much more sense than to just fund it blindly

switch between normal thruster based movement and performance saving movement for NPC's does not happen at 10000m (magic number) but is based on configured view distance + 2000m

VeryHard -> Brutal

- trigger siege offer, offer which when accepted generates a new Siege mission against random enemy faction.
- Very Hard mission difficulty (can spawn randomly during mission generation with 50% chance compared to the others, Triggered sieges are always considered as Very Hard).
- Very Hard missions do not take rarity into account, meaning legendary ships have the same chance to spawn as common ships.
- Separate list of physical rewards can be configured for siege missions, these are added on top of the standard physical rewards for successfully finishing the mission. Both Planetary Sieges and Free Port Sieges apply for additional rewards if configured.
- NPC factions are compensated when they create ship sales and offers and not just assigned money on game load (so it does not happen that NPC faction runs out of money and stops creating offers until next game load/restart)
