Gallery sim had custom pose, can't find in Mods folder to delete

My sim had a child with someone from the Gallery through cupids corner, who had a custom Gallery pose. The child now also has this pose, and other sims are starting to acquire it when they age up from child to teen. I've deleted my Mods folder, cleared my cache, deleted other package files the game remakes when reloading anyway, repaired the app through EA and searched all my game files to no avail. Where else would this file be hiding? It's really annoying and I can't figure out how to get rid of it at all, I don't even use poses myself. I use **bleep** and MC Command Center, no CC or other mods.
