Problem Posting Adult Events

The sim on which I have a club has been set to Adult today.

I have tried to post Events today. The first time, I clicked the "Yes this is a Mature event" box like normal, and got the error, "Cannot post a Mature Event on a PG sim." Well, I know the sim is Adult, I see it right now.

So next I tried posting it without clicking the Mature box. The Event shows up as PG.

Has anyone encountered this problem, and can advise me on what I need to do to post an Adult event?

I'll answer my own question.

Given my last experience with Live Chat, I wasn't expecting it to be useful. The people to whom it was outsourced don't seem to be too helpful. But this time I got help from a Linden on Live Chat, and it was helpful.

Apparently this is a bug of which Linden Lab is aware. Even though the Event shows as PG, I'm told it will be filtered from PG searches, so just go ahead and post as PG. Unfortunately, until the bug is fixed, it will show in Search with the PG icon rather than Adult.
