I'm not completely sure if this will work, but i had the same problem at some point. I also hv a T-mobile Samsung Galaxy Note 2 and this happened to me awhile back. I was never able to find a solution online for it so I just common sensed my way through it. My phone was having a bunch of glitches.....I don't even know how to explain them.
Root was on and off just like it is for u.
TWRP was acting really weird: when ever i would flash a new rom or wiped data or system, nothing would happen; its as if TWRP was just telling me everything was working, when nothing was working at all!

What I ended up doing was reverting to the stock image. I used Odin to flash the stock image. then i flashed a custom recovery, then i rooted my device. This time there were no problems. If you are gonna try this just make sure to back up all important data. And once again, im not sure if this will work but try it out and lemme know!

I think I may have figured out what is happening here.... I think the SuperSU app and SU binary are getting messed up when the SU app updates from the market. This would explain why it will sometimes break over night.

I tried flashing SU in recovery a bunch of times and it doesn't restore root but if I re-flash my ROM, I usually get root back. I think the difference is that all the SU components are getting reset to default when I re-flash the ROM but when I flash SU, it is just applying it on top of the existing root/su.

I was checking some settings and I found a work around that seems to restore root without having to re-flash my ROM....

Settings > More > Application Manager > ALL > SuperSU > Uninstall updates

Then, I reboot the phone and root is restored when it comes back up.

I have tested this by updating and uninstalling the updates a few times and I lost root every time I updated and it came back every time I uninstalled the updates and rebooted.

I disabled auto update in the market for SuperSU, so hopefully this issue stops happening. If not, at least I have an easy fix.

Thanks to all for the suggestions & help!
Let me know if this fix helps anyone else!

I just built a rom and Im was having issues with SuperSu staying. I normally dont have any issues flashing supersu and having it work but for some reason the only way it worked was to update the app, to 2.01, from the PlayStore and then letting it install the SU Binary by rebooting into recovery.
