I haven't played the latest version of the mod yet (RC14)...
How it was before:
a player uses Spirit Link on enemy troops, and then gains mana by killing them. That is, the mage's mana after the battle is 100% (full), even if all enemy troops are killed only with spells.
I suggest: Spirit Link is only applied to the player's troops.
Added after 22 hours 26 minutes

another suggestion: make it possible to choose a city specialization (at the start of the game).
You haven't played the latest version, and you're already criticizing it. Genius 🤣
