Vaguely similar problem here.
My first round at St. andrews was full of Flash crashes - I hadn't cleared my cache(s) yet. I did this and it seemed ok then. I haven't had any "oh snaps!" since that with Google Chrome. Note I was set to "unavailable" - before the update (which is now "hidden") If I remember correctly, I changed my status to avaliable before teeing off a second time. maybe there was a strange issue with this naming change there? I may be mis-remembering, but I think it might have said "unavaliable" instead of Hidden when i logged on this evening.
and then...
Playing a multiplayer stroke play game. BPB back. on 17 I decided to change my status to "busy". The game then crashed - but it wasn't instantaneous. It was after my opponent hit his tee shot and the ball landed. I think I changed my status while he was at the tee. I did not get an error message at all - the screen just sort of blinked - and then I was at the resume game screen. strange.
and then...
Just now, with the wgt forum page up, I changed my status to "Hidden" - which logged me out! I suddenly was just at the home page, not logged in, and the client pop-up was still there - no error, but I was logged out there too.
It was like I hid from myself.. ha ha
P.S can I get a status option that says "tired of all this freaking snow!!!"
