FYI: Just installed the A20 mod and tried to run a dedicated server, it kept closing the server console after I saw a flash of red text, didn't know what was happening. Lots of googling with no answers, then found some server hosting site provide a list of possible world names for this mod, and the one that came with the mod download (DFalls-Small1-NoCP) did not exist, they all end in NoPEP. I changed the NoCP to NoPEP and it works.
