What happened to the parkour lobby?

Bug Description: So I got stuck in the parkour lobby, while everyone else in my match was actually able to play, and I had a friend spectating me. The colors of the lobby got all changed...like the dark blue clay turned magenta, and where the cobblestone walls are under the wool parkour blocks turned into stone slabs. I was so confused, and still am (this was a while ago).
Screenshots: I literally can't find them, but this did happen. It's just really weird.

This has been here for a long time. It just happens when it is really laggy
