So today my husband played SK until he ran too low on energy and got off. Well, I haven't played in a few days myself so I hopped on about a couple hours or so after he got off and found that my energy was only at 14. We don't share an account. Also, I know we've been able to get on and off before without problems. So is this a new thing where they're determining players by their IP or is this just a bug? (Sorry if that last sentence sounded confusing.) Anyway, that's all.
Its an intentional feature where any "unpaid" accounts on the same machine will share a mist pool. If either of the accounts have purchased CE, then that account gets an independent mist pool.
If they are both paid accounts, something is amiss.
