I've heard from a couple users now that have experienced what you are describing - they suddenly had duplicated annotations and some of the annotations for them were placed incorrectly. I've been trying to figure out how to reproduce this issue and have not had any luck so far. I did add some extra code to ensure that annotations are cleared out while the database is being updated, so this could possibly help. I do think the issue is probably related to the automatic saving feature. So if you go into the annotations editor settings and uncheck the option to save the file automatically, this will probably prevent the issue you are seeing. I am going to keep looking into this though.

As far as clearing out the duplicated annotations, bring up the layers window in the annotation editor, and hopefully all of the annotations are grouped based on when they were created. If that is the case, you should be able to select half of them (the duplicated half) to remove them all at once.
