Thank you for your suggestion. I will ask Mr. Black to notify our players when the servers are going to be restarted.
Unfortunately, we, Community Managers, usually receive the warning 5-40 minutes before the restart and very often we have no time to prepare our Community. But even if we do, we can't say for sure when the servers are going to be restarted. The time frames are never specified.
I understand that it may cause some in-game losses and I recommend you to contact our Support Team if you have them. They will check the information about updates and make a decision in your case.
Also I recommend you to clear your browser cache and refresh the page after you receive a message that the game server is being updated at the moment. This will help you to login as soon as possible and minimize any possible losses.
I hope I could help you with this situation.
