There is something going on with the SL system this morning (7AM-8:30AM). People in a large number of groups are talking about Bake Fail. It seems lots of people are staying gray.
There is no good work-around. Some have solved it by relogging. Some have solved it by waiting.
DO NOT clear your cache. That just makes it worse for you and everyone else.
I am not seeing the problem. So, it is not affecting everyone. But, it is affecting a large number of people.
