I don't know if it's a bug or a Glitch but this is the third day i have logged onto Spiral knights with the same amount of energy that i had when i logged off i would log off with 6 energy and log on with 6 energy me and my friend share the same computer but i don't think that should be a problem now i would like to know why i havent been regenerating energy it's really stressful if anyone could help i would much appreciate it.
Mist energy is shared by all accounts that use the same computer unless (or until) one of those accounts buys Crystal Energy with real-world money. Since you said you and your friend share the same computer, I think this is probably the issue. Any purchase of Crystal Energy with real money, by either account (you or your friend) will separate the two accounts on the computer so that you'll each regenerate mist separately.
