Another short update today, it will cover an interesting issue that was reported during recent beta testing of the next patch.
The mod, it does not work!?!?!?1
A change that was made in the patch (addition of a seperate late multiplayer cost for units) broke mods that edited unit costs as the mods did not contain this new value. They would crash on loading the game. Now not wanting to leave people who play some of the more popular mods with a game that doesn't load for reasons they would not understand, we are adding support to the game so that mods without the new field in them will still work once the patch is released.
Though modders, I would advise you to take advantage of the new field once the next patch is out.
So...beta update?
The foruth and version of the next patch will be done soon and will enter testing.
There will be a changelist posted closer to the release of the patch.
