Game Crashes Whenever I Open Quests

All day since like 11:00 am the game has crashed when i try to open the Quests tab, at first it wasn't worrying, but then energy refills happened. I eventually had to open the tab by clicking Ghost>Find>Achievements. This happened on both my mobile and Bluestacks. i found a work around, by going through the achievement link in vader, but this only has like 30% success before it gets stuck loading. I have tried uninstalling and reinstalling, but the problem persists.
