I'm looking forward to see those.

Basically levels above 10 are untested and may or may not increase the
strength. We can't even guarantee that they ever return a move.

In this case the engine (tested with 3.3.12) seems to get lost in
complicated tactical reading while searching for combination attacks.
It may be worth investigating whether there are ko issues involved
there.

This is a known bug in 3.2 which was fixed early in the 3.3.x series.
The patch is available in
