Most of my downloaded custom zombies maps have suddenly become moderately or extremely laggy to the point where they are unplayable, and I have no idea why. Any solutions?

Hey guys! Here's my video tutorial of the steps of the Swan easter egg. Hope it helps out anyone still trying to get it!

IMPORTANT: Now with updated download links! If you were experiencing trouble playing co-op before, please download again!
