OK. I have another big section of cave that is currently broken due to mysterious therion metapost errors. I've tried to track it down but I don't understand well enough to do it. I am getting this error: ! angle(0,0) is taken as zero. l_arrow->...d(angle(direction.infinity.of(EXPR0))- 90)shifted(point.infinity....l.5565 ),2); The angle' between two identical points is undefined. I'm zeroing this one. Proceed, with fingers crossed. I assume this means that I have two points on top of each other - but I don't know in which scrap, or which line, so it is not practical to find it. The offending files are at: http://trilogy-gw.aleph1.co.uk/~wookey/files/soundriver.tgz http://trilogy-gw.aleph1.co.uk/~wookey/files/soundriverpic.tgz (includes scans) It seems that if I include any of soundriver2_s1 soundriver3_s1 or soundrivercrab_s1 then it breaks. soundriver2_s1 is particularly perplexing as it is a straight bit of passage with no areas in it, 3 stations, and not much detail - seems to me there is very little to go wrong. I did have soundriver3_s1 working last night I thought, but not now... I am afraid I am going to keep sending you these until we work out some better debugging system :-( or I get a lot smarter.
