I noticed this in the FTB Launcher.
The Direwolf20 pack installs Twilight Forest but it is not listed in the launcher main window for the pack.
Only a minor issue, who ever is doing the launcher updates may wish to update the mod list for the Direwolf20 pack to reflect the mods it installs for the next launcher update. Again only a minor issue that as far as I can tell does not affect anything of importance.
