I'm not sure if this was the case before Pinehurst No.2 was added to the list of courses. I might be getting long in the tooth, so apologies if the grey matter isn't functioning as it should!
When creating a multi-player game and clicking on stroke play, the CTTH courses still grey out but Pinehurst shows as a playable stroke play course. Of course, at the moment it isn't....
To get the list of stroke play courses up in the old way, and in order to be able to select Oakmont, Kiawah and RSG, I then have to click on the right arrow to advance page & then left arrow to be able to see those 3 courses. IIRC, before Pinehurst was added, the only courses displayed were the stroke play ones.
Not a major issue but just something I'm making the WGT team aware of if they don't know about it already. Of course it will be correct when we can play Pinehurst as a stroke play course (after playing CTTH @ No,2 I personally am really looking forward to this!). Cheers.
