I started working on stone walls some time ago, they were about 75% complete, but when I logged on for the first time after the latest patch, I noticed that stone wall construction had stopped and wooden palisades started building on their own. I didn't even have enough influence for the the palisades.
As you can see they are overlapping with the stone walls and residences and I can't finish the stone walls as the palisade has taken precedence. I most certainly do not want it.
You can see both wall construction buttons greyed out at the same time due to active construction but only the palisades are actually buildings. I've paused the construction before exiting the game.
It may not be patch related but perhaps this fix has somehow caused it?
