I was playing on the Ragnarok map on single player. When Extinction came out, I uploaded my character from the Ragnarok map and then started an extinction single player with him.
When I decided to switch back to the Ragnarok map, I uploaded my survivor from the Extinction map and opened up the Ragnarok single player. When I got there... my character was listed twice (these aren't copies of each other, as they have different food and water levels displaying).
Is this normal? And if so... is there a difference between those uploaded characters? (They are both level 105.) I'm thinking I'm going to have to carefully manage these saves if every time I'm switching maps I will be creating a ghost of my character in the obelisk.
