Steam EA build 2014-02-11 rev.29505
First campaign upon reaching Magetobria, the Suebi units inside wouldn't come out and engage. Had delayed getting there in order to clear out the Tigurini (Ancestral Debts). Approached to about the defense radius and took over the farms south and west (since keeping your legions fed in the field is a bit tricky and I haven't got the hang of it yet). Got the "not one word spoken" dialogue and the new objective, but no-one showed up: all four units were still in the (Sequani, allied) city.
