(From the perspective of players...I lost a day of progress to a bug? He, they knew about about it and didn't fix it? Time to look for another, more stable game... I bet you don't want to lose players on this so put up that warning message!)
So you are threatening a forum moderator, who has no control over the game, to add a warning message that will only benefit a very small percentage of the players? Elements does not give in to terrorism!
And unless the game says they aren't supposed to, it IS CONSIDERED A BUG, WHICH IS THE DEVELOPER'S FAULT, because players do nothing they aren't supposed to do.
How did you come to that conclusion? Players aren't supposed to hack this game, yet they do. I just proved you wrong. Just because you aren't supposed to do something, and the game doesn't directly say it, doesn't mean it's a bug. It's good that you came here to ask about this, because true, not all people understand how games like this work, and now you know better. I liken playing in two instances of the game similar to place a quintessence on a spark. No where does it say you aren't supposed to do it, but at the same time you are allowed to do it, doesn't mean it's a good idea.
Adding "Playing the game in multiple computers simultaneously from one account can result in lost progress" to the login screen is the absolute minimum you can do for your players, if you are too lazy or for some reason unable to check for double logins.
Too lazy? You most likely don't know how to code a game, let alone how to code something to check for double logins. You cannot rightly say the developer is being lazy by not adding this. Maybe he is busy doing more important things, like, oh, i don't know, making new cards. (

By the way, is there any way to split an account into two? Is there a way to change the password? No, so I'm stuck with sharing it. I'll solve the problem by limiting the time of the day when each of us can play, but you shouldn't intentionally let others waste their time when all it takes is a warning message.
There, see. You found a solution that works.
