Hi,
you can't walk over walls with 0 HP, when this mod is enabled. Also as client you can go through walls (the server will send you back behind the wall after moving too far).

Steps to reproduce:
- Start a game with "[Updated] Complete Your Map" mod enabled, as client (eg. enable caves).
- Build some walls.
- you will be able to walk through the wall (and send back if moving to far)
- attack the wall with weapon. You will be able to move over it.
- Now disconnect and connect again.
- now you can't move over the 0 HP walls anymore. Also the bug when moving through build walls is gone. At least for those walls build before the actual session.

edit:
If I disalbe "Walls" in the settings, the bug is gone.
If you are able to fix this bug, I think you should check, if this also happens with other objects.
