Dear players,
We have been informed by many players through our support system about this issue that started happening after reaching local/market midnight: game reloading multiple times while using the training feature. This situation has been reported to our developers, which will resolve the issue as soon as possible.
Creating many tickets about this issue will delay the resolution of other requests as well as wont make the fixing of this error. Please accept our most sincere apologies. Thank you for understanding.
Your Hero Zero Team.
