That new function for moving directly a tag by drag n drop into a same file looked to be a good idea, but the execution is a total mess. Unwanted moves on surrounding tags, many bugs, puts a total mess in tag libraries...

You should have tested it before release it on last production version, it really makes drag n drop totally unusable. I pass 70% of my drag n drop time to correct ans rectify unwanted modifications, this is really a shame.

So I'll probably add manually the tags with keyboard direcly in file names, it will be far more faster right now despite the 100% manual procedure.
