So, am sure you know me on Twitter, but I just got an unexpected issue in my iPad 2 iOS 9.3.5
Steps to reproduce the error:
Sideloaded the BLIZZARD iPA
Opened and Clicked Jailbreak and jailbroken at first click, after that apple logo and boot to Jailbroken state, then opened cydia and cydia started preparing system then again apple logo and booted then opened cydia and 12 upgrades was available, so I clicked upgrade and after upgrade I click Restart Springboard and after that it stuck on respring like black screen and after 1 minute it turned screen to black fully, then I click on power button and slide to unlock then I seen all system apps gone except appstore apps.

Hello using v1.3 Blizzard JB 9 I noticed the tweak options in settings disappears after rebooting and re-jailbreaking. Tweaks I tested RePower, NoSlowAnimations and Speed Intensifier.

Another thing I noticed is when I tried the tweak called RePower, that gives you an option to power off, reboot, respring when you hold down power. That whole thing disappears after rebooting and re-jailbreaking and trying to use it again, it will just give you Power Off.

If I Uninstall Blizzard JB reboot and reinstall Blizzard JB and install say tweak NoSlowAnimations, the options show up again in Settings but disappear again when I reboot and re-jalbreak. I've also reinstalled Blizzard JB rebooted first before installing any tweak re-jailbreak and then installed one and it will show the tweak options but then disappear again. when I reboot and re-jailbreak. I attached two images showing the options and the RePower menu working before rebooting.
