The server was just updated to 1.10.2, you know the drill.
Make sure to update your clients to 1.10.2, and report any bugs to THIS THREAD.
As a side note, I've been toying around with the idea of doing "Rally Days" again, where I promise to be on the server between a certain set of hours on certain days. I find this encourages people to log on and group up for events. Let me know in comments or on the server if you think this is a good idea.
