You'd be surprised what a bad date here or there does to a ship's cfg... We've been finding stuff in FotRS Ultimate on probably a weekly basis. Look what CapnScurvy found in our thread just the other day with the "Stock" mistake of November 31 still being on the game's "calendar". Stupid simple, but when you're talking about thousands of files, "needle in the haystack" might be a more apt description, especially when you're talking about date relations between several files, being dependent upon each other...
- I haven't played it in quite a while (OM, that is), but I remember a discussion of this years ago, so go through some of the old threads. I do not remember any resolution. Of course, we are talking about a bunch of plaque in an old brain here...
