I installed this game into my computer and enjoyed playing it and I wanted my sibling to join. But since they don't have a computer; I decided to let them play on mine. So they made their own account and knight, but we noticed after they started that the energy bar was low (instead of being full like a new game would), and when logged off and I went to mine, I saw that the energy bar was the exact same as my sibling's.
So when they went through a level, not only did my sibling loss the energy from going to the level like normal, I loss the same amount of energy not being logged on.

I know earlier I had internet problems, but that was the DSL.
So is this a bug, technical problem, that the internet going out in the middle of the game glitched something, or something normal for shared computers?

Please let me know.
