Deleting a Group

Hey, I know topics somewhat similar to this have been created, but they all seem super outdated.  I have not changed my groups plugin, so I think this is an issue not created by me (unless I have some hook causing it).  When I go to delete a group, the icons/images that are used for it are not deleted in the data folder.  I have looked at the groups/delete action, and it looks like it is deleting them, but it is not.  I noticed it doesn't do any error checking to see if $img->delete() returns false either.  Is anyone else having this problem?  I have tried writing the code manually in my own action and that hasn't worked either.  I feel like the filestore might be pointing to the wrong directory (and thus the resource I want), but I can't say for sure because I don't know enough about ElggFile (and ElggFile->getFilestore() is a protected function :( ).  Any help would be greatly appreciated.

Thank you in advance!
