Native posts duplicated

Using:
Feedwordpress 2014.0805
Wordpress 4.1 (just updated today)

I am having a situation where every wordpress post generated on the website is duplicated several times. Some of the feed posts as well, but literally every post generated on the website is duplicated 4-10 times in a few days to a week after it’s posted.

I have about 30 plugins total installed, I could list them to determine whether anyone here knows of any conflicts (or it would be great if the developers had a list). I can’t really turn off all plugins and see if the problem goes away as it usually takes a few days to happen. Recently I updated the theme and added some social media feeds, as well as the Feedwordpress Advanced Filter plugin to get images for syndicated posts–I just updated that to 0.6.2.

Any hints appreciated!
