You've not provided your query in any of your replies so I can't advise much. Am not seeing any issues in my tests (aside for _comprofiler manipulation from backend). Please provide the query you're using as there could be a problem. Also note if you have the query conditional based off a field and you're setting that field AND giving the user a subscription from backend it will fail, this is again due to order of execution.. CBSubs fires before profile save does.
