If you have an old tent, it will be destroyed: You can only create one tent per character
....
And where did you find that? i had trouble finding this damn forum.
only way you can have multiple tents is to get a have friends who are willing to make a shared tent (go with him when he is making his tent, in the random encounter map tag him and let him make the tent, this way you can see 2 or more tents on your map and can access all of them without loosing any of them)
