big loss

1. What's your exact gamer name?
Aeonera

2. What happened?
at approx 5:40 to 6:00 gmt+12 people started to be logged off but could still talk, we were told we were being hacked by mike,(who it had happened to) and were told to log off, the server was then (to my knowledge) shut down for some time, when i logged on again at 9:00 gmt+12 half of my overground railway track had been demolished and my giant HELLO! sign had completely dissapeared

3. Why do you think this happened?
Edit: i think i have figured out what happened to my minecart track. when nader blew up ZOMG's house i think it fired a tnt onto my section and blew it up >.> be more careful with ur tnt next time plz.

4. Is it an item/robbery?
yes

5. If its an item, what is it? (IF THIS IS SOMETHING WITH LOW VALUE (COBBLESTONE, DIRT, SAND...) IT WILL BE DENIED!!!)
around 30 railcart tracks, a number of dirt (which i dont care about) and 104 glowstone and 147 stone (not cobblestone)

6. Approximately wat time will u be on? (I strongly suggest u convert the time to australia/Sydney as it makes it easier), if u cant please specify:
4-5:30 almost every weekday
•Timezone gmt+12
•Where is that timezone (NZ = gmt+12 = new zealand) nz
Time Zone Converter

7. More details:

no i looked and placed the tnt carefully, tnt didn't out of zomg's area and i looked around the area after the tnt blew up to make sure..
Is this still an issue?

Did you get a screen video of it, it might look cool in videos advertising our server
