World Conquest works incorrectly with several leaders

[Discontinuum]

Game and System Information

• Version: 1.18.0

Description of the bug

Some eras allow to get an additional unit with canrecruit=yes. It would be logical if losing one of several leaders will not affect the game (as there is the commanders mechanic) but in fact losing any canrecruit=yes unit results in defeat/triggering a commander promotion

Steps to reproduce the behavior

No response

Expected behavior

If there are several canrecruit=yes units on the field, losing one of them doesn't result in a loss/commander promotion
