Unfortunately what with life and other commitments, I haven't had the time to work on this project for some time, and in comparison to Ashes of Erebus, the other RiFE continuation, there's just a colossal amount of work to be done.
Add to that the issue that what works on the disk-release of Civ4 BTS doesn't always work on the Steam release, and vice-versa, which makes troubleshooting a problem, and it's just more than I can currently deal with.
