Symbols breaking apart when moved

[jodym58460117]

Subject says it all. I use symbols OFTEN for tech pack creation.  When moving these symbols, all the elements break apart.  I have been using a 1+ year old version of Illustator that seems to be OK, but that version is no longer available to download in the CC options. 

Please focus less on Ai, and fix these core bugs in your expensive software.

Is that still happening after rebooting the computer and resetting the Illustrator preferences?

Is that also happening in a new file with new symbols?

If so, can you please post a test file?
