I just answered to this question : How to enable Survival Mode in Fallout 1.4 Patch. The problem was that the mode that the user was looking for was not implemented yet. The answer is good at the moment, but when the patch in question will be released, it won't be anymore.
What is the good thing to do in such a case ? Should the question be closed or deleted, or should I edit my answer when the patch will be released, so that it explains how to activate the corresponding mode ?
