Strange. I was sure I'd installed both the 13th May installer and the 27th May zip update, so I don't know where an old version of "quests_reaction.c" would have crept in.
I've used "windiff" to compare the modified version to the one in the 27th May zip file and, apart from the modifications I added, they're almost identical. The one other difference is just before "case cartagena_snoring_starts", where the modified version has "//pär" and the version from the zip file has "//pär". I don't even know what that's supposed to be, let alone how it got changed, but the "//" ought to mean it's a comment and has no effect anyway.
(The zip file shown here is "b14_b3-5_wip27May2014.zip". Perhaps I should use a zip file from 2015. )
