Ah, you're referring to the Arid Canyon act 2 museum mod. Yes, it's missing because of permissions. If the maps were allowed to be included certain parts of the presentation likly would have been fixed and or upgraded such as making the emblems actually emblemsI could've sworn either an older version of this mod or a separate sort of archival mod had an earlier development version of Arid Canyon Act 2, but that doesn't seem to be present here. Is there any reason why? Is it a permissions thing?
