This is a bit baffling...

In a custom battle, I can't seem to get rid of the old 'Celt Lesser General' as a leader unit. I have safely swapped out the standard bearer, and have tried adding extra lines to the unit description to add 'officer' models ( this works fine ) but the overall General remains unchanged.

Can anyone point me in the right direction for this ? I have the model..... it's defined as a unit in descr_model_battle.... I just can't get it to replace the old model in a custom battle!
