Many apologies for that brief downtime. I am currently unsure of what caused it. Yggdrasil has restarted the server and it is currently online (as I know you know, since you are online now, haha). When he gets home from work tonight he will look further into the logs to see if he can find out what caused it. I know several others have reported random disconnects throughout the day as well. As always, please do not hesitate to submit a support ticket if you guys see anything else that is odd or glitch-y. We will do our best to correct these issues.
The issue was corrected but still working through some bugs on it. Currently you can not analyze rock shards, sorry its a modloader issue not even a mod issue. But if you were effected by the downtime of the server please bear with me once i get everything fixed I do plan on compensating the people that were effected.
