doors open when I leave game and get back on

Whenever I leave the game (by pressing pause, exit to menu), it will automatically open my door to my house. even if I don't leave the game, just quitting to menu and getting back on. Sometimes even pausing the game does it
*What I expected to happen was my doors would stay closed

*What actually happened was my doors opened

Steps to Reproduce:
1. Put a door down
2. exit to main menu
3. get back on that world
4. opened door with no effort (for the TRULY lazy)
