Kinda hard to tell which game you're refering to if you post this in the Lobby. ???
I'm assuming it the orignal so I'm moving this to that forum.
You can apply the[red] V1.20[/red] patch over top of the V1.10 patch and if anything it might improve things. I'd recomend it. :yes
For some reason LHS doesn't have the V1.20 patch listed in their download page.
If this is for BW2, The V1.1 patch is required before installting the V1.2 patch and also recomended. But you can't use Phoenix with it. :no
