Thanks for that -- I have yet to get particles and sounds to appear consistently on client maps. I'll take another look.
Engineer escorts might be a good idea, or maybe just for the besieged town in the towers to make things a little harder for the attacker.
I'm not sure how to make things any easier for bots to deal with characters inside towers.

Also, only one of the North American servers (Empires_of_Faith_MMN) should be able to handle sieges right now.In the other, you'll probably get the open field. I just need to have the other one restarted, which will hopefully happen shortly.
