I had latest version (febab7e, no dcnn) play on kgs for some time (about 
70 games) and everything looks good, it's as strong as before.
So it does look like something funny is happening on my side. I might be 
on to something but need to investigate further (my cloud company 
changed cpu recently and we're compiling with -march=native ...)
At any rate sorry about all the fuss.
