[BUG] Aryamod V7.3 Youtube Lag and Twitter not saving my profile.

Hey guys, I've installed this rom and I'm so happy with it. It has all I want in a rom. Thanks to the creator. I have a couple problems whit this rom, and I'm searching for a solution. Youtube lags when I watch videos at 720p and 1080p quality (I haven't tried 480 and 360p), and Twitter app doesn't save my profile. I log into Twitter, I use it normally, but when I kill the app and I enter again, I have to log in again. Does anybody has the solution for this? Thanks!

YouTube App Missing From Android Marshmallow

After installing Marshmallow from the system image, I realized the YouTube app was missing and was available for download from the Playstore. I checked the /system/app/Youtube folder, and found an apk there that returned a "parsing error" when attempting to be installed. I reflashed the system.img but the issue persists.

My one hunch would be that it was overwritten when I flashed ElementalX and SuperSU, as I only have 385 kb remaining in /system. My fear is that, if this is the case, something more important could have been overwritten as well.

Thanks for any help.
