Reply To: RE: Class diagram error
I think that the root cause of a problem lies in the past - when multiple elements were copied between diagrams or when they were grouped and ungrouped. From version 4.93, this problem should not occur anymore. Unfortunately, this fix cannot affect the saved files.
If the problem you described is caused by something else, please, let me know - if you could also repeat the steps, which lead to it, and send it to me, you will help me a lot.
