Hi guys i hope it is an easy question someone can answer for me: Which table determines the techtree? I know that the most are bound to the subgroup in the factionstable, however i am curious how it does work regarding the "the last roman" campaign. How can i transfer a techtree from the Belisar Campaign in to the Grand Campaign? Just selecting subgroup roman in the factionstable doesn't work. With that i just get the normal roman techtree (i want to do it with the Ostrogoths) but without any units and buildings bound to it. If i change it in to east or west roman i get the buildings and the look of the romans for my ostrogoths, but thats not what i intend to do.

So the obvious question would be what do i need to change to get the Ostrogoth Techtree from the Belisar campaign to my Ostrogoths in the main campaign.
