Update: Further testing showed that there were a number of other maps that weren't working. I disabled all the mods I'd installed in the last few weeks, which solved the problem. I've narrowed it down to one of the mods I installed for FS, which I now do not need on this install, as I couldn't get it to work with FS, so I made another clean one. I'm not sure exactly which one of the four it is, but the problem lies there.
