Again you are using a misunderstanding of singular extensions.  This does *not*
mean that one move is clearly better at the root so extend.  It means if one
move is clearly better *anywhere* in the tree, then extend below that position.
I'll bet that as you let them search, maybe for weeks or months, the eval will
continue to drop and a new root move will keep popping up, until eventually
the truth shows up...
