"I see you!" glitch!

Today I was at sector 4 of Herbert's hq and found ALOT of penguins (probably coming home from school) trying to go through! There were so many it made a white bar under them:

 

When you walk across into (Sector 5??) the next room, you can see into that room, just without background color! Here are two pictures of penguins walking around and trying to get across (I promise, absolutely not any editing!):

 

Weird right? When I went to go see herbert on the French servers, and people crushed into the door, this happened too! I must be because there's so many penguins!

 

Waddle on,
