Sorry again for not meeting my own timelines ... things just keep coming up and taking me away from this project.
Luckily, I have finally found the time to finish it off! There are three .xml files attached - one for each set in Thranduil's Light and Shadow block. Copy those three files into your
Gccg => xml => Lotr folder and add the lines:
<cardset source="light.xml"/>
<cardset source="twilight.xml"/>
<cardset source="back.xml"/>
to the file
Gccg => xml => lotr.xml and you should be able to use the cards in GCCG.
The only problem I know of is that when I run GCCG, the cards from all three sets appear jumbled together into a single set. I'm not going to bother fixing this unless it is affecting people besides me, so please let me know if you experience this (or any other) problem.
Also please post if you notice any typos in the file. There were some errors when I copied the .pdf into a text file, but it's possible I missed a few. They're generally easy to fix, I just don't want to go through and proofread all 360 cards myself.
