I've read previously, that using furniture, such as fridges for example, effectively creates a "wall" for zombie path finding thus making them useful for barricades etc.

I've read the pinned post for path finding, but I'm not sure if this is something that would also come under the survivor AI path finding being difficult - But I have noticed that survivors can, for all intents and purposes, climb THROUGH fridges being used as barricades.

Just watched a dude climb into my base, through a broken window that was also barricaded with an industrial fridge. I'm not sure if they can freely pass through fridges that are being used to blockade a hallway for example - I imagine not but who knows?

Just a bit of a bummer that I can't keep people out of the ground floor of my base is all.

Any confirmation if this is something that cannot be resolved, due to the AI survivor path finding?
