In my case “auto success range from last seen location” was the problem. It’s auto success when pawn not moves in range and then max age is not counting. I thought max age is counting down also and not influences by “auto success range from last seen location” when pawn not moving. Set “auto success range from last seen location” back to -1 solved my problems.
