Hey
Unfortunately, there hasn't been an issue with memory loss with the Benefit Hall.
We continuously ask players to remember to manually log in on the calendar as it's something that can be forgetful.
If you feel like this is a bug. Feel free to report it to the "Support" icon on your client/browser. And submit a ticket including your Client(Full Screen displaying Client time and CPU time) and calender.
Thank you for understanding. This post was last edited by Tobei at 2017-3-15 20:53
