Age Modding?!?!

[Frostmourne27]

I just tried to mod the ages of two units, the Arch-Theurg and the Grand Master. Code follows:

#selectmonster 42
#maxage 70
#end

#selectmonster 41
#maxage 70
#end

#selectmonster 223
#maxage 75
#end

For some reason, this only sort of works. The computer takes one look at my code, and changes the starting axe of the Arch-Theurg and Grand Master. So now, not only are they old, they have unnaturally long lifespans. Agggh! I've made it worse. (I was excpecting it to to change lifespan - I just didn't think it would change start age too.) How can I make these units start relatively young? I was planning on doing a mod that removed most of the age related nuisances. (I don't think it's a stupid feature, I just think my favourite races shouldn't be hit so hard ) Suggestions anyone? Or have I done something stupid with my code? Looking over the mod manual, I see three commands: startage, which doesn't seem to be quite what I'm looking for, older, which seems to imply it might take a negative number, in which case it could work, and maxage, which apparently doesn't work.
