After the update I've noticed troops tend to walk around the base instead of through in.
In particular bears and wizards, who are supposed to go for defenses, will no longer smash through the walls where they are deployed.
For example, I attacked a base that had a cannon behind 2 lots of walls in the far top-right of the base. I deployed a lot of bears and some wizards just next to it but instead of the bears/wizards smashing the 2 lots of the walls... they instead walked all the way to the other end (to the far top-left of the base) just to smash through only one lot of walls there to destroy the watch tower behind it.
Before the update bears would go for the closest defense to where they are deployed regardless of walls. Now it seems they walk in circles around the base until they've destroyed everything and then they break into it.
