It's not logical to demand WGT to influence Flash updates which are solely under Adobe's (and your local) control. To revert back to former versions, visit Adobe's service area.
Corwyn:
I noticed something odd in an MP game last night (20-odd hrs after the downtime): we went to extra holes, and I think it was my attempt to grab Replay links (using Menu>SaveReplayofLastShot>Share>Copy method) that sent us into disco-land.
I'd been doing that no problem throughout the match in regulation holes, but the disco problems appear to have prompted by trying it during extra holes.
Corwyn, it has been reported several times before the update that the game either discons when going to the extra holes or by certain action during this phase. Thus, no new bug :(
