Is leadership working ok?

None from above. I was mage and just was blasting my way through the enemies. Never used sacrifice except in couple of battles very early in the game just to see how it works; and I never used any undeads.
This happened to swordsmen and to royal snakes but I went through the game mostly with those 2 units (replenishing them from my reserve).
At first I thought it is due to some artefact losing morale but it was not the case. And I used the frog woman without any kid for the whole game.
At the same time I am absolutely sure I didn't remove any leadership artefact too. And it is not due to the rats on the stick things - I know they reduce the leadership and I was carefull about them.
And no diplomacy skill either.


Edit: the only thing I can think of is the enemy using something wich increased my stacks over the starting size. But have absolutely no idea what it could be.
