A few weeks ago I played an excellent AOK Campaign, called Boudica vs. Rome. I left positive comments and gave it a thumbs up. A few days ago I noticed that in my Comments list that the mention of my Comment said that it was deleted, and then when I tried searching for the Workshop page, it turns out that the whole Workshop page for the campaign had disappeared. It used to be at https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=1671965556

The Campaign required The Forgotten, as well as saying "use the mods [IA] Italian Architecture for Independant Mod, which recommends using "[IA 5.8] Independent Architecture" (https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=893953860).
It had 5 good scenarios:

X Scenario 1. Roman Gold. (I beat it on HARD.)
X Scenario 2. Subordinate. (I beat it on MODERATE)
X Scenario 3. Dishonored. (I beat it on MODERATE)
X Scenario 4. IX Legion (I beat it on HARD)
X Scenario 5.(I beat it on Standard)

My best guess is that the Designer deleted it, because I can't think of a reason why the Steam Workshop would. The Campaign generally worked, although there was at least one minor glitch on Scenario 5, ie. that the AI in London seemed to delete all the city's walls for no reason.
Unfortunately I unsubscribed from the Campaign after beating it, but I still have my savegames.
I doubt that I can somehow restore the campaign using the savegames, and I doubt that the workshop would allow that anyway.
