I logged in and every monster I had was gone all I had is a firetaur what do I do?

Was your account connected to facebook? If so, log into facebook. If that doesnt work try uninstalling and reinstalling, then connecting to facebook.

If it wasn't connected to facebook, try sending in a ticket tho support.

@Jennifer-Lopez-Pogorzelski

And can you explain more ?

did you lost your monsters on fb or mobile ? did your level reset to level 1 or you still keep your level ? was you trying to re connect to fb after re installing the game ? do you think that your Fb may got hacked ?

@Haka-Taka mobile i my level still goes up but I have no monsters I also tried uninstalling and reinstalling then signing into Fb

If your level is Ok but you missing monsters then it is not like connecting issue or multi fb account switch .. Probably someone logged to your account either from your device or hacking and deleted them . contact support by sending a ticket to see id you can revert your account back
