I sold. I had hoped for soe communication fro the company after symbol change, but it takes too long (for me). Don't understad why they did that, and remain silent. But maybe I sold too early (wouldn't be the first time, lol) and they start filing soon.
And to answer your question. Yes, I've seen that, but not too often. Anyway good luck and as soon as they start communicating, I'll buy back!
