Another attempt to fix the save problem some people are having.

Fixed bug causing mod incorrectly affecting player/companion equipment

Fixed camels being equipped with horse armors and added item modifiers persistence after loading a game.

Improved comparison system for accurate equipment evaluation
Cavalry keeps lances/spears, infantry keeps pikes (no more random weapon swapping)
Optimized processing to prevent stuttering during equipment updates

Added save/load functionality, troop equipment modifications now persist between game sessions
All equipment sets are preserved with their unique item configurations
No changes to core upgrade logic or performance

Fixed a bug where troops could equip items from other cultures; cultural restrictions now apply correctly, with neutral troops exempt.

Fixed a bug where troops could equip items one tier above their own. Now equipment is restricted to their appropriate tier (with elite exceptions).

Fixed camels being equipped with horse armor and vice versa.

Minor changes.
