Thanks for reporting.

This whole end-game is wrong, loosing pawns is already not necessary of course. In home test from 6k1/5p2/6q1/P6p/1P4p1/K1P2P2/3Q2P1/8 b - - 0 75 using Minic 3.29 versus Minic 3.30, the score is clear

White vs Black: 21 - 0 - 0  [1.000] 21

100% win of course.

Could be TB related I guess

Sure, even maybe TB + TT issue. What has always been strange is that it is not happening that much often and almost never at home where I have 6men but of course non 7men

Thanks for this new example. I'm finally able to replicate the issue at home. I'm on it with good chance of patching soon.
