When zombies come in contact with walls, they are invisible. I think this might be a consequence of players not being able to actually hit walls. This made zombies a real problem in buildings. I would also sometimes not recognize it happened right away, and get punished by the zombie badly.

Either find a zombie that is stuck in a wall, or knock a zombie into any wall with heavy attacks. Don't stop attacking. Eventually the zombie will be invincible to your attacks and will attack back unimpeded. If you continue to stand your ground you'll be killed.
