 ## Features/Improvements
 
 * **[Campaign]** Weapon data such as fallbacks and introduction years is now moddable. Due to the new architecture to support this, the old data was not automatically migrated.
+* **[Campaign]** Era-restricted loadouts will now skip LGBs when no TGP is available in the loadout. This only applies to default loadouts; buddy-lasing can be coordinated with custom loadouts.
 * **[Campaign AI]** Overhauled campaign AI target prioritization. This currently only affects the ordering of DEAD missions.
 * **[Campaign AI]** Player front line stances can now be automated. Improved stance selection for AI.
 * **[Campaign AI]** Reworked layout of hold, join, split, and ingress points. Should result in much shorter flight plans in general while still maintaining safe join/split/hold points.
