We have been experiencing an error when 2013 surface fills are regenerated in 2014.  Essentially a feature prior to the surface fill is modified, but it is unrelated to the surface fill, and SW will not be able to regenerate it.  When you open the feature and hit the green check mark, you get the following message:

"Please select edges for blending" just does not make sense for the Fill feature.  Trying to recreate the feature leads to the same error.

Does anyone have a fix for this?
