This question was posed by enderland:
Wasn't Rey cold on Starkiller base? Shouldn't this have impacted her somehow?
And it was promptly closed (by myself) as a dupe of this one:
Why does Rey wear the same outfit in different environments?
Since then, it seems to have been reopened (by users ibid, enderland, Wad Cheber, Null and alexwlchan) which confused me somewhat since my answer to the dupe question specifically deals with the question of whether Rey was cold on the Starkiller base (Yes, she was) and whether it impacted on her (yes, she briefly wore a jacket).
Given that my answer to the first question specifically answers the second question, why was it reopened?
