Disappearing Act

I was recently creating a map and I was using stunt ramps to form a bridge. However, I phased in the 1st ramp into the bridge only to have it disappear, or so I thought.

You can now only see it from certain angles, and zoom distances. However, it is still fully functional as a bridge. Has this ever happened to anyone else?[

How very odd…

Never seen this! How strange.
