I am, but since whoward released v72 of VMC which fixes the LAN lobby issue right after the release of 9/1, something tells me we'll see a new version of the CP
very soon. Sooner than it would make sense to start a new MP session with the current beta.
Yes, this happens when the name of the mod's folder doesn't match the one specified in the modinfo file.
example:
(3) CSD for CBP (folder) vs. (3) City-State Diplomacy Mod for CBP (modinfo) vs. City-State Diplomacy Mod (CSD) for Brave New World (v 27) (modinfo-filename)
(4) Civ IV Diplomatic Features (folder) vs. (4) Civ IV Diplomatic Features - CBP Edition (modinfo) vs. Civ IV Diplomatic Features (v 10) (modinfo-filename)
Just copy all the missing folders manually, their contents were included in the override-files during the pack's creation, so that's no problem at all (as a matter of fact it even might break the modpack when you don't copy them).
Achievements are enabled via the DLL of the CP. An 'achievement-enabled' DLL is included in the 1/3 modpack, and I will include a new one in every stable version.
cheers!
