It happened again last night.  I won't start another game till it's fixed.

Cheers,

I haven't had this problem in the games I've played, so I don't know what's causing it in your games.

I have the same problem which only began when I purchased The Dead World DLC on steam last night.  Previously using the steam package with the 3 DLCs both in 1.3 & 1.4 this bug did not appear.  I can recreate this bug every time I play with the currently installed DLC.  I would love to have a way to turn off or remove DLC packs; this would allow me to play the game while this bug is being hunted.

This is a screenshot showing the extreme distance reached by the bug; it also took over my outpost.  http://i.imgur.com/vlZNXC5.jpg

This is a screenshot showing the border encroaching on my kingdom. http://i.imgur.com/vRphM4j.jpg

I had to send out scout to even see the new border, which was not revealed.  My Arcane Monolith which is extremely far away from the bugged kingdom was taken over by the border bug.  When a city near a resource expanded it's border, it couldn't expand in that direction because the extremely distant foreign kingdom was building on the resource!

Thanks for your continues efforts to patch the game.

Will you also be pushing the fix for Morrigan's Call, since that was checked in for the next patch?

Thanks Derek, I love the game and I love your involvement in it.  Since the WOM days it has been polished and tweaked into an excellent game, bordering on classic or masterpiece.

It's wonderful that you've been able to live your dream too!

Anyone know if this patch was released yet?

I looked at the files and I see that stardock included some background stats for CotS in the undead stuff. At least they worked with some compatibility with CotS.

So I just encountered this bug again. 

I noticed it in the Winter of 221 when I was informed that one of my watchtowers had been destroyed by enemy forces.  The watchtower in question turned out to be halfway across the map in the middle of what used to be another Channelers territory.  This particular channeler had her main city border crushed down into a newbie sized 9 square in about 3 turns.  I don't know how long the bug ran before I noticed it and I am uncertain of any particular contributing causes.  Discovering the bug rendered that game pointless so I closed the game and came here to post.
