I have now carefully checked the Story scripts and this version (also on Steam Workshop) should work:http://www.mediafire.com/download/kiog32hnn6e1qbk/JourneyLoneWolfv6.2.zip
This time I properly tested it instead of simply recompiling it like I did with the previous version. At the very least, I was able to start a new game with one character and speak to Bairdottr. I did redo all of the script changes to make sure I didn't miss anything in the files, so the possibility exists that one of the later things (like Zixzax) won't work if I forgot to redo those specific changes.
Speaking of changes, the culprit appears to be part of the INIT section of CYS_General. The previous version used databases to set who couldn't trade, while the current version uses a function (or at least a different database) to set who doesn't trade.
Are there any good tools for comparing two different text files for changes? I feel like such a tool would be useful in the future when Story changes occur and everything breaks.
