is this a known bug/abuse issue?

Hi!
i made a map for a friend who just started with TAB.

i placed some enviroment on the ground (ruins) and when you place a wall on top of it,, the infected seem to completly ignore the walls?

is this already known or did i just discovered something game breaking?

cheers!

walls are automatically ignored by zombies.
only when they are in the way, the zombies will attack them.
also wasps. (only difference - wasps do noise, so if nothing is around them they'll be attacked too.)

yes i understand that.. but the issue is,, they are running against the wall that is in their way... they HAVE to go through the walls to get to the command centre, so that's the reason why i asked if it was known. :)
