this afternoon I got a high commander dragon egg, then I hatched the egg at the hatchery, but suddenly the dragon city was error and asked me to reload the page. After I returned, the egg was gone, it wasn't in the warehouse or it wasn't in the hatchery. Please help me!

@m-syafri-surya You have to ask the support for help.

@bettina-löffler thanks for your help, i have sent an message to dragon city support
