Yes, there was a brief server outage. Luckily with all the new moderators in-game we were able to get it back up quickly.
We put in place some more logging the other day, so hopefully this will tell us what's going wrong. Although it could just be the sheer number of players online pushing our servers to the max.
If anyone has lost any units or crowns from this recent outage, let us know at firstname.lastname@example.org
and we will sort it out.
