Experience point of some troops is not saved

[tos1]

At least for "Squire", its upgrade right ("+" sign in party member list) is lost when the game is saved.

(I saw this also in v8.1 at least for; Bravo, Braavosi Trainee, Northern Archer, Squire. I guess the v8.2 have the same problem for these (and probably other) troop types if no one fixed.)

- How to reproduce it/when/why it happens:
Hire at least one Squire, wait or act till he has right to update ("+" sign). Talk to him/them, select "Tell me about yourself", and check his/their experience point. Save the game and reload it. Check the "+" sign and the experience point again.
(Please check also for Bravo, Braavosi Trainee, Northern Archer, and many others. ESPECIALLY, the quest of "a dozen Skilled Bravos" is painful for the player because the upgrade right is reset every time the game is saved.

- Game version (and steam or downloaded):
AWoIaF v8.2, Warband v1.174 downloaded
(Note: v8.1 + WB v1.167 has the same problem.)

I think this is a warband specific issue. How things are saved or loaded is hard coded so i have no access to any of this.
