Playing as England, I've got 2 units of 40 English Knights and 2 units of 60 Retinue Longbowmen plus some other units in Toledo, which is a full-built up citadel (including canons) with a Master's Swordsmith guild. The game is offering to retrain these 4 units, and no others in Toledo. I've been retraining these 4 units over and over for many turns, and the training isn't sticking somehow.

If I right click on the Retinue Longbowmen in the unit window they show xp 0, but if I right click on them in the retraining window they show xp 2. In the unit window they show no xp chevrons, and silver shields. There are no other Retinue Longbowmen units in the citadel other than these two, so the two units its showing me in the retraining window have to be the same two in the unit window -- even though they show different levels of experience!

The English Knights are a little more confusing because I have three units of them in the citadel. As far as the unit window is concerned one is xp 4 and the other two are xp 0. In the retraining window I have 2 units, both that show xp 4 if I right click on them.

Is this a known bug with a known workaround? I think I saw this before in this game with Sherwood archers, but that eventually sorted itself out somehow. I don't know what I did that got the units fixed.

Thanks
