Training Problem with Axemen

[Jagger]

Has anyone seen this. I have a new Gaulish Axemen. I can hire and fight with them. And I use to be able to "retrain" them. Now I can't retrain them.

I was fiddling with a lot of different things over the weekend and obviously I changed something.

Anyone know what file and function allows retraining of troops??

You can still build them in that province?
Strange... I thought if you had the needed building to hire them you could also retrain them.
I haven't found any reference to retraining in the files yet, so I think you can't make a unit non-refittable but I'm not sure there.
Maybe you can post the related parts in the text files?
