This is very strange and I can't seem to be able to find out what's going on. I've got uSync set to "don't import" and I do manual imports whenever a change is deployed to production. However, even though it used to work fine, what's happening now is this:

I run "report" and see I've got n changes to be done. I then run "import" and it tells me that some changes were done (and some not found, which is expected). I go to "view usync actions" and remove any orphaned actions. I go and run "import" again, same thing. No errors, nothing in event log (even set it to debug on log4net.config as per another post here), but nothing is changed. Report keeps on telling me there are changes, and import seems to work but does nothing. I even re-deployed and ended up with the same set of things (including the orphaned actions) again, and did the whole cycle, ending up at the same point as before.

I checked permissions on the production server - they're okay. I ran the checks from within Umbraco, and they're okay too. I can't think of anything else that might be causing this strange behavior. Any ideas?
