Ah yes, this was a while back. I still don't know if there is an update there, perhaps to can fill me in. Essentially, someone claims to have found a serious vulnerability, but we still don't know exactly what it is? Maybe I got that wrong. Anyway, for this post I'm specifically thinking of something more recent in which a dev stated that he was quitting LN and focusing elsewhere. I believe it was a different L2 like Ark. Does that sound familiar?
