for the past 10 hours ive been poking around hammer. I've been doing fine until recently. I made my base, walls, ect. and added chunks of breakable walls. the problem I am having is the infected have NO urge whatsoever to break in, making my map pointless >.....<

I can get screenshots if you need them, but its really pissing me off if I cant make this work.

any suggestions.
any.

Thanks.
