A very quick assortment of answers:

The only way to move a group of units forward (or indeed in any direction) without losing formation is to re-drag the formation at the location you want them to move to. Yes, this is annoying.

Watchtowers and forts can only be built by generals. Move the general to a suitable site then click on the upper of the two big circles just to the right of the centre of the main interface. That should bring up a sheet offering the build choices.

I can add a bit about the technical bits to the next version, which will appear to cover the 1.2 patch.

I haven't used onagers in a siege with high walls yet. Try placing them a bit further back; if they are too close the projectile presumably won't gain the height to make it over the wall.




Can I request all future questions are posted in the guide thread please? I am having a hard time keeping up with all the work this guide is generating, and needing to check just one location less will make my life that little bit easier. It also makes it more likely you'll get an answer in a timely manner. I'm currently working with something like a 2 day lag between receiving a message or post and actually answering it.
