I've fixed a number of bugs in the last couple days related to the "Update songs if matching files are found", so if you've been using that setting, it might explain some of the issues you've been seeing (in general, that is a setting you will want to use with your workflow). I also messed up the duplicate file detection in the last update, so it will treat duplicate files as a conflict now instead of ignoring them correctly (or taking whatever action is appropriate for a duplicate file based upon selections). The best thing to do will probably be to have you update to v1.8.9 after it's released, re-test to see if you still experience any problems, and if you do, I'll work with you to ensure they get fixed.

Thanks,
Mike
