+1 to fix this, is is annoying to see this error show up when the point of pausing is to remove the workers so they can do something more important.

If it is intended for a paused building to complain about workers, then I request a change in intended behavior.

Edit: after skimming some of the other bug reports, I think this needs a "bad behavior" label
