Carpet Overlap + Doorbell Stick

I decided to quickly categorize two common glitches today- the 'Carpet Overlap' and what I call 'Doorbell Stick'. They run rampant across the game and are simply annoying.
The first glitch occurs when you have a significant amount of lag while going from one person's den to your own. The flooring and wallpaper will overlay on your den.
The second occurs when the first person to enter your den leaves. The 'doorbell' icon will stay.
