Right, it's not an issue we can solve with logs (they don't point to the problem, nor give a hint for the solution), so our only choice is first-hand experimentation, and that can't be done without a device.
Developer are working for free to give us this custom rom but many people aren't respect them. Xiaomi EU team didn't force you to use their custom rom so stop complaining. If you not satisfied with their work, then feel free to change your rom. No one going to stop you. Be respectful to other people please.
This rom is "BETA" not "STABLE" so use it at your own risk.
People, (while it may not be a good idea to jump in) keep nandroid backups, if possible before updating and even if you don't and an app breaks backup your device contents and apps (with app data), format and restore them later. You can probably flash a previous rom just with a factory reset and not a "wipe data" action, preserving ~everything inside internal storage (not apps though). A nandroid backup might be much quicker though in case something happens. If it's been 2 weeks since that problem exists then you could probably help yourselves by reseting the phone (it'd probably take less than 2 weeks...).
