Oh I was unaware that this bug existed - what other bugs are in the game?
And what device are you using?
The app is nice but it's so laggy after you unlock a few methods or you automate them(at least for me on a galaxy s5 mini).
edit.
about the login issue i tried to delete the app and reinstall and it worked but after i closed and reopened it....same error so a fix is a must xD
Definetely a must! I haven't experienced this issue myself but I will look into it today.
Today I will release a performance improvement. It will however not require you to update the app itself - it's a server sided improvement. This should help with the lagging a bit.
