Yeah. Its possible for things to go very odd sometimes in a design. Last 
one I had to redo from scratch (not just due to the glitch, but because 
I didn't think the design through very well). It seems, some place in 
the process I deleted, or connected, something wrong and got what I call 
"ghosts". Sides, or faces, which don't connect how they are supposed to, 
and produce non-solid surfaces. The result exported to cae, which I was 
trying to use to import to Second Life, but nothing, not SL, or Blender, 
or even the program that exported it in the first place, would load the 
thing. Most just failed without an error. Second Life said something 
about a value being wrong, or something, when it failed.

Unfortunately, finding these problems, never mind fixing them, in the 
programs that create the meshes, is usually totally impossible. :( 
Maybe, something that let you handle "discrete" points, like Rhinoceros, 
could do it, but most can't handle those, let alone say, curved, without 
at least a single "face". Some won't even allow single faces, and 
instead require solids. So, when you accidentally mangle one of those 
solids, its impossible to correct the problem. Sometimes those things 
will also mess with the exporter, or even, as in my case, create a 
seemingly valid export, which just flat won't import into anything at all.
