Interesting that you've notice no battle being fought too.
10K worth of Rogues just marched into the capital of Nothoi on Beluaterra, fought no battle, and immediately started a TO.
Fully defended city with both militia and noble regiments in house BTW. And level 5 walls.
I think we've got a bug here...
Once that bug gets fixed you guys will be fighting those rogues without the wall XD
