I have been running this ROM for a couple of months. I have Xposed installed, I currently am running only 1 module, the SD fix, to stop the bugginess with the SD card. I have XInternalSD also downloaded and tried using it, but I wasn't finding it working all that well, so it's currently disabled. I am having problems with the SD card irregardless (seems to be a general issue with Marshmallow), often the camera app crashes when I try to take a picture. The other problem I have noticed is that when the battery gets low, the phone will sometimes get in a mode where it keeps rebooting, multiple times, I have to take the battery out briefly in order to stop it.
