Normally, when you are copying&pasting objects, EasyEDA initially shows the newly pasted copy with the same designator as the original object, and then - after a brief pause - updates the designator to something that is not currently in use. This is slow and irritating, but at least it works. However\, if during that pause you press "w" to start wiring\, the copy object immediately disappears\. What's worse\, from this moment on the copy renaming mechanism stops working and all newly pasted objects will retain their original designators\. Should you now try to update the PCB\, \_original\_ objects will get modified with new connections and MOVE AROUND\, making a mess of your existing layout\. And if you think that maybe you will get some help from component panel on the left \- tough luck \- it is now dead\, too\. The only way to get out of this situation is to reload the project, but if you saved it before - it's backup restore time. Now, this bug has been in EasyEDA Pro for months. I bumped into it repeatedly, but always was too busy to write up the report, thinking that it is so obvious and easy to trigger that surely the developers and/or testers will find and fix it soon. Today I lost an hour of work because of it and frankly I am no longer confident that even basic issues will ever get resolved in EasyEDA Pro. Guys, can you PLEASE hire real testers? It is clear that your current QA process is inadequate for the software of this complexity.  <br> <br> <br> <br> <br> <br>
