The fact that the whole "zombies can go through every single wall" issue hasn't been touched either? Ridiculous.
This is the single biggest bug in the entire game right now, one of the simplest to fix, and they aren't doing a thing about it. I am this close to just quitting because of that one thing.
Please fix real issues instead of minor bugs.
It's not a simple issue to fix. The devs have been working on this issue for a while now and if you have paid attention to the blogs they gave some specific reasons why this happens and what they are trying to do to fix it.
Duplicate of #77 (Zeds clipping through objects [PRIMARY REPORT]).
Please read the comments on that issue. The devs are working on it, but as shogodz89 already stated, this is not as easy to fix as one might think.
Please be patient. Thank you.

Johnny
