My Hours gone...

Seriously? You didn't even read the announcement made on website?

All hours were reseted to 0. Reason? There was a bug that could be fixed only by recreating the table and adding the same values would have created that bug again and people could cheat the system that way like 3 already did but didn't managed to buy anything.
You should have spent those hours before as there is no reason to keep the online hours and not thread them.

Since you get 5 credits per hour now you can easily get them back. Oh and remember that most servers do not reward you for online hours so don't make a dramma out of this, afterall is for the sake of the server not for your own sake so this was a 'must to do thing on the list'.
