I created a Survival World with only the water mod.
When I build a log door i can close it but after it is closed when i press [F] it acts like an inventory.
log doors will not open once closed, shows inventory when hovering over door frame. The stone and plank doors seem to work like normal doors. You can close the log door as a door and have the normal options for configuring for it as well.
I made a topic in the steam forum as well
