We moved form SW 2012 SP5 to 214 SP3 and have serious issues with the save as references functionality.  Somehow, when we use find/replace and change an assembly and it's references to new names, the first part in the assembly becomes a surface model with all of the assembly components in it.  We have several users experiencing this.  Any of you seeing it?  I am going to try and figure out the exact steps to submit a bug, but was hoping someone may have already figured it out.  Thanks,

Gary
