The Wonky Door

[Dan R-M]

Thought I'd venture out of "Everything Else" for this one, since it seems like it could pertain to building in general. I hope you'll let me know if the issue is another SMY special
Putting it simply, my door is wonky. Specifically, the deadbolt and latch don't line up well with their sockets, so I have to lift and wiggle to get the deadbolt in its hole as I turn the key. (As a sidenote, I wouldn't even use the deadbolt - or lock the knob - if the normal latch would work. I just want the stupid thing to stay shut in wind.)
My [conventional] contractor father-in-law told me it just needed to be shimmed square and that would solve the problem. I respect his knowledge, but I also know that conventional buildings don't flex quite like a yurts do.
So I put it to you, the experienced yurtists: is there hope, or will I need to teach my family how to do the "door wiggle"?
