Hi anyone who is stuck at 91% and cannot log into the game:
This is a very tricky bug. Despite the fact there are some players reporting it, we are unable to reproduce it on our end. This could be a phone system issues which only occurs to a certain type of Android phones. Our only way to work around the problem is to rewrite the game saving system, and we are already working on this. As the new system will require heavy testing to ensure everything works properly, the ETA is 2-4 weeks.
At this time, I'm afraid manually transfer the data is the only solution. Or we can send you a reminder when the new system is ready online.
Once again we are very sorry for all the troubles caused.
