Rick,
You'd be right if I were first deleted it. But, as I wrote twice, first I had a movie, than imported bio and that's how he disappeared from the actors list. JCVD, btw, is the last movie in my list.
Nostra, I made some screenshots, then I discovered that I had JCVD invisible record, and after updated bio, I guess, that invisible JCVD record got only his credits for the movie - actor, producer, etc, but his credits from the visible JCVD were gone. I deleted invisible JCVD record with CTRL+YES and updated all, and everything seems ok now. It was important information for me that you couldn't reproduce the problem, meaning that something was locally wrong.
How I discovered I had invisible JCVD record? In his bio, that movie's font wasn't red-colored, but only blue. How I got that record - don't know.
Thank you guys.
