Maybe it's just too big? Dunno how that's measured

Normally caused by a cylinder or brush with more than 28 sides, although having said that, you say you copied parts into the map from outside? You want to check that during the transfer, you haven't misaligned any of the brushes. By that I mean , have a look at all the non standard brushes, anything that isn't square, and check that they all mate up with the 1 unit grid. Brushes that have been clipped or vertex manipulated do not copy across really well and can cause this error. Transforming clipped or Vertex Manipulated brushes can cause the same thing.
Check the face points of each brush and make sure they are aligned on the 1 unit grid. Also check any cylinders or brushes that have more than 28 faces (Oh and spiral's as well, or anything made with the arch tool)
