Okay, if any mod feels like, move this.
So, yesterday I used up all my ME on my account and logged off. After that, my brother logged in from the same computer. He also used up all of his Mist then logged off. So, today, I log on, I have a bit less Mist than expected and I could've sworn I had about 80 more CE when I logged off yesterday. Oh well. I play until I run out of mist and log out, then check up on my bro's acc. He has near 0 energy.
So, I'm guessing that the accounts get linked or something? Fair enough, it stops alts I guess, although my bro won't be happy, lol. But is it possible that yesterday him playing on his account leeched of the CE from mine? That would be kind of a low blow considering he is in T1 and a full run nets him about 5k at best while I get easy 8k from T2. So basically, my energy is worth more than his, especially CE.
PS, would using his mist tank on that account fill my mist as well? Or would he leech from my CE if using the energy from the tank?
Mist energy is shared between all free accounts on a given computer. Crystal energy should not be shared, though, so I'm guessing that you accidentally spent some of your own and didn't notice.
