When I set up the guard tower and chose someone to became an guard or ranger, his health changes correctly as the setting "guardhealthmult = xxx" , but when I quit the game and login the game again, their health reduce to the default health(not 20 health, it is 20 + their "strength" attribute I guess).
Actually, I don't know wether the health add up is correct at the first time, becase I set "guardhealthmult = 1.0" and the guard health add too much as I excepted.

The first time they become an guard(knight or ranger)

I quit the game and login the game again
