I am currently working on modeling a 2-story commercial building with Openstudio 1.14. Everything seems to go ok with geometry creation and surface matching. But then after, and only after, I rename the spaces/apply them to the correct stories/apply space types/apply corresponding thermostats, I get a completely unnecessary surface subdivision, and the following errors:

Warning:  A surface was subdivided because of connected geometry.
Added new surface Surface 633
You should check your geometry carefully for mistakes.

Removed duplicate drawing interface for object Surface 551
  Potential duplicate of object Surface 633

Is there any way to prevent this from happening? I did the space renaming/space types/thermostats all as one step so I don't know which caused the problem. Also, I don't know if it makes a difference but while building the geometry I used the BCL surface intersection/matching program because it tends to work way better than the "surface matching" icon in the plugin.

This is odd, can't think of why renaming of objects would impact geometry. If you re-open the model in the SketchUp plugin after intersection, but before re-naming you don't get this warning? If you send file to OpenStudio@NREL.gov I can take a look at it. Could be pre-renamed with instructions on what to rename, or pre and post-renamed, but before re-opening the renamed file and getting this warning.
