June 20, 2026 - Season 1 - Update 26 (Mod Version 1.0.26)
New Save Game is Absolutely Required


New & Changed Features


  • Updated the mod for Stellaris 4.4.

  • Added 2 new NSC classes for the Bioships - a "Ravager" Dreadnought class and a "Sentinel" Explorer class. (These are the only 2 classes we are planning to add to the Bioships).

  • Increased the fleet command limit from 1000 to 8000, to allow for larger fleets after the 4.3 fleet capacity increase.

  • Removed the Destroyer's Escort Carrier research upgrade and changed the Escort Carrier sections to automatically unlock upon researching Cruisers, to avoid long waits for RNG to pop up the tech.

  • Due to ongoing bugs and issues, the NSC Advanced Ship Behaviors have been removed from the mod. As a replacement, we highly recommend the Spacefleet Tactica mod, which is significantly more advanced than the NSC behaviors were. You can subscribe to that mod here: mod_detail.php?publishedfileid=3696204283

  • Temporarily removed the Fleet Mothball feature until its code can be rewritten to eliminate the bugs.

  • Added special coding to the Flagship which will prevent it from being instantly destroyed when using Emergency FTL (It can still be destroyed by the Emergency FTL damage effect if the damage is higher than the ship's remaining HP).

  • Hyperlane Generators & Removers will no longer count towards the megastructure limit.


Bug Fixes


  • Fixed a bug where the Nemesis ships still had the old pre-4.3 fleet capacity numbers.

  • Fixed a bug where the tooltip for the Eternal Vigilance perk still referenced the starbase defense platform policy, which was removed in vanilla in 4.3.

  • Fixed a bug where Frigates were not able to access Level 6 and higher reactors.

  • Fixed a bug where the damage multipliers on the Minuteman and Harpoon torpedoes were set much too high (they were still on pre-4.3 numbers).

  • Fixed a bug where colony and construction ships were not getting access to cloaking devices as they were intended to in a previous NSC update.

  • Fixed a couple of minor typos/bugs with the NSC overwrite of the Eternal Vigilance ascension perk.



Mod Backend/Coding Changes


  • Moved all of the NSC ship classes to its own nsc_ship_sizes file. (We still overwrite the vanilla 00_ship_sizes file to change necessary things on vanilla classes)

  • Added scripted trigger is_nsc_activated = { always = yes } to the mod to help with compatibility with other mods. (common/scripted_triggers/nsc_scripted_triggers.txt)
