On niveus in ele, building the arm next to some boxes.  I then mark decon it and build another on top of the first.  The arm that appears to be floating in space is no doubt touching one of the boxes for the crates.  I then build a medi under the arm, which causes the model to drop down to the ground and exist at the same location as the medi.

Erk. I've seen stuff like that before, but not quite this well documented.

Someone should really fix the model size vs. bbox size mismatch...
