possible bug?

[Dogboy]

We are playing v 3.08 multiplayer. This turn, Man stormed Ulm's castle and took it. He then was informed that the newly stormed castle was beseiged by barbarians. A barbarian attack is a common random event. But, according to the turn sequence, (pp. 71-72) in the manual, random events should occur 10th (10: Random events, "Like it says. This is where theose Fortune/Misfortune events happen"), before resolution of battles ("14, Movement battles: battles caused by movement are resolved"), followed by 15 Castle storming: Castles are stormed and battles resolved. One might imagine that the random event moves the barbarians into the province after which battles occur in a random order. But even if that is true, storming (15) should occur after movement battles (14). Any theories about why this could happen, or is this a genuine bug? If so, what should I do by way of allerting Illwinger/Shrapnel?

I also observed on the same turn that there was a graphics bug in the storming battle. The walls of the castle were transparent grids. I've played multiple games with v 3.08 and not found this bug before.

Thanks.
