So I'm working on my next map and it's going well. However, I noticed something odd.... I can hear the sound of a Paladin and after some searching I think I found the source.
It's mysterious, this small little blue wireframe poking out of the ground at the lowest depth appears to be the source of the Paladin sounds, but no matter what I do I can't seem to select it at all to delete it. In the wireframe mode, it is a lopsided cube partially under the ground, with a few other lines. Any body got an idea what it is, and how I can get rid of it? Please?
