I've searched around the patch notes and can't find anything about it. I'm randomly taken out of stealth in wvw, many times right after I enter it. There's a large boom and I'm revealed. It even happens in friendly territory right after a B/P HS combo. It happened twice tonight on an engage and completely screwed me up. The enemy is not within in range to cast any reveal skills either. I'm sure everyone knows, but I haven't been following the patch notes for the past few months.
