Getting armor, weapon and valor upgrades via retraining

[Shahed]

That's happening to me right now.

I had about 15-16 Turcomen without any armor, on campaign against the Eastern Rebel cities.

While they were on campaign I built a padder (?) and then a blacksmith for light mail armor. Then I bring them back about 15% manpower depletion. I put them in que to retrain at the blacksmith thinking I'd get the armor PLUS manpower upgrade.

Sure enough they were retrained, brought to full strength. but NO armor upgrade at all, not leather or light mail. I paid however, for a full upgrade.

So now I have the Barneys knocking at my Western gates and I'd really like to have this Turcomen army upgraded before the next campaign.

Can anyone help ? Am I following the correct sequence/procedure ? Is this a bug ?

edit: had a look in the manual on pg 30-31 of the mainland europe-english version, according to that all you have to do is build the buildings required and an armorer. The higher the level of the armorer the higher level it can upgrade.

I'd be happy if it upgraded to light mail. That would be enough... lol !
