Strange thing: Owen kingdom, Enemy host at castle but no siege notification and no note under castles name ( happend 5 times now ). Low garrison.
only other observation: adventure guild quest , Joan Zwiebel, after finishing the alternate quest (Spymaster) , First you can command her like patrol, some time later she becomes border patrol, continuing the Last task given. Not sure here wether it‘s WAD or effective bug/ glitch - as it is Not a broken behaviour per se.
