some bugs with towncenter ?

maybe it isnt best supfoldet to post my question but I hope it will be fine

So going back to the topic i wonder didnt you found out that if you hiring mercanieres for towncenter (or how is it called ) all you milatery troops start to respond slower to your comands - the more hired mercaneries fro town center you have still alive , the slower respond from all unit you get , and they also start to atack later ...
so is it me or more people saw it ?
P.s. sorry for bad english
