Automatic hibernation does not work topic

Hello,
I know already what you are thinking about, here one more who talks about the same parameter over and over, always the sane issue and same problem, posted 1 billion times. Well:

1. Yes I bought the paid version
2. Yes I have installed xposed module and activated boost mode
3. Yes I granted SuperSU permissions to the app
4. Yes I activated the auto hibernation mode
5. Yes it worked for 2 days, after what it stopped (so it works, the problems is why did it stop? I did nothing)
6. Yes I have a rooted device
7. Yes I restarted the device many times
8. Yes I tried many times to do the same way as the first time worked (I did the same procedure)
9. Yes I read many topic about it, and I read the FAQ before writing here
10 Yes I have the latest build version available in Play Store 2.6.1
11. Samsung Galaxy Note 2 device, dr.Ketan ROM v12, AGNi Kernel 4.3.7, TWRP 2.8.5.0, Android Kitkat 4.4.2

Any other question to ask before give me an answer to explain why does not work any more?
Thanks in advance to those who will help me to solve this mystery :D
