1) I've read in the manual that empires can play with their taxation rate. How is this done? I can't find a way to change tax rate for either Roman Empire in the campaign and there is no other mention of this in any other part of the manual.
2) Sometimes I can't seem to train units although I have enough gold and levies. Is there anything else the units require other than gold and levies? And before someone asks, no, there is no other unit already being trained in the province.
3) Can anything be done with APs other than accumulating them for empire maintenance.
4) Is there any way to see the numbers and types of embassy tokens I have?
5) Heretic missionaries often appear, seemingly controlled by one of the Roman Empires (playing the campaign with red team), but I can't move them or tell them to do anything. Is there anything that can be done with them other than trying to kill them with strategems?
6) Leaders of both Roman Empires are Arians. Can the Empires be converted to Arianism and is it a good idea?
7) My Franks got 2 hordes at some point. These hordes have options to settle and construct towns, but they are grayed out. I've tried moving them to a Western Roman province I gave them in Foedus and also to an independent province to the east but the options still remained grayed out.
I'm sorry if some of these features are explained in the manual already. I failed to find them. I can't read the beta-maunal pdf while playing because the game doesn't support alt+tabbing and reading it on cell phone is really difficult. Thanks in advance for any answers.
