I guess the question says it all.
Start a custom game in private, name it, and then add AI via the slots after choosing your map in the lobby.
For the speedy reply. I was beginning to think that something like that must be done. Many thanks.
One can also open World Editor, open a melee map and then modify the player slot settings. Once done, save it as something else and then test the map. This allows the use of cheats which is not possible in multiplayer.
Custom games are not working, it won’t let me create any against the AI since it keeps knocking me back to the custom games screen each time I hit create. Also I don’t know where this ‘world editor’ is.
Server teething problem. Should be resolved over the coming few days, as Blizzard always does.
Battlenet application. Warcraft III tab. It is one of the options at the top. It will launch with Reforged graphics (even without owning it).
