Ranged infantry still don't switch target when enemy gets into range

[This game is laggy]

If you read the update notes, you'll come across this line

Ranged Infantry switches targets when enemy troops come into range.

which sounds pretty great.

Unfortunately most of the time it doesn't seem to work that way.

Here are a couple of videos showing this issue

You'll notice that the crossbowmen keep on attacking the mill/market even when the defenders come into range. They only switch targets when the defenders whack them a couple of times.

Near the end (~0:45) however, they do behave as described in the update notes, i.e. switch to attacking enemies when they get close enough. Unfortunately, they don't act like that consistently.

All except 2 of the crossbowmen ignore enemy defenders when they come close. The crossbowmen seem locked onto the buildings they are currently attacking and they only attack the defenders when the latter hit them directly.

Out of the 6 crossbowmen attacking the Town Center and Temple, only 1 (the bottom one) switched target to attack the defender when the latter comes close.
