I tried the "Host" function and I get the same error message.

See screenshot - text should read "...and can be tied to posts and trees". However, note that animals currently can *not* be tied to posts, either fence posts or the taller wooden pole, so maybe it should read "...and can be tied to trees"  

Someone out there in the modding community really, really needs to either revamp or design from bottom up another mod that handles this task.  I am currently using the Zombie Virus Vaccine Mod and the ability to throw corpses onto such an implement would make this 100x better and more immersive.  That by itself is a good enough reason.  But if you play PZ at all, then you know the burden of looting and weight constraints.  I constantly have to stop and start in debug mode due to my game not playing well in debug alone.  Yes its cheating but I tend to move a huge amount and re-organizing is almost impossible with the realistic weight settings in game.  So please, if you are that person, or you know that person, build the Mod...  We ALL could use this type of mod and I am completely surprised no one has revamped or started there own build.  If its due to waiting for 42 to be stable then I completely understand.  I am brand new to PZ and have only been playing for a few months.  But already I have amassed over 650 hours due to being disabled and or retired which ever you choose to use.  I have been waiting to find a game that draws me in with the level of immersion and its been under my nose this whole time lol.  Please guys, get it going and if so drop me a line to inform me.    Thx again Dren.

Another example of what I'm talking about. I can see the inside of this house and i haven't even been inside it yet. How does my character know the layout and which doors are open/lights are on?
