I'm still on SVN 1125.
As Harald Bluetooth I decided to conquer back England after the English spawn.
So I didn't develop the English cities, just kept building huskarls; and before the spawn moved all my troops towards Wales, leaving the cities unguarded.
My plan was to found a new city near the stone resource after the spawn, wait some ten turns (to avoid my troops joining the enemy) and attack London first.
Just before the spawn Ligeraceaster and Norwich were cancelled to towns (and I found it normal).
The problem occurred at the moment of the English spawn: I let Londinium and Eboracum flip, and no English troops appeared. Just a few in Lisieux, not a single English soldier on the English soil.
I tried a quick game with the Moroccans just to see what happens in England: Londinium is erased and troops and settlers appear on the spot.
I reloaded a few turns earlier, and playing with WordBuilder I gave the English cities to Robert the Bruce and emptied them. Then again, Londinium erased and English troops and settlers on the spot.
