I think you're right about both of these.

In the first one Crafty likes Qg6 after 30 minutes. Score is -0.92 (advantage to
Black). Score for ..Rd8 looks about the same, maybe a little better.

In the second one, Bh7+ is also Crafty's choice but as you say may not be best.

I'll probably remove both of these from the testsuite.
