WeiDU (153, available now) will uninstall changes made by STRING_SET (and "forced string references"). <Talks into wind> Despite this, you should not use these features. </Talks>
Moons ago someone mentioned some --biff-get problem with BG1. Thanks to the generous support of viewers like you I now have a copy of BG1:ToSC installed on my hard drive.
If the people who were having that problem would be so kind as to give an example command that fails, I'll look into fixing it. Yes, you listed the command before ... but I've since forgotten. :-) Note that I don't want to install Dark Side, so please stick to standard ToSC.
