A fairly simple wing with blending, in 3.17.1 the load distribution is smooth. With 3.25 the load drops markedly near the center of the wing. I'm not entirely sure, but I get the feeling the 3.17.1 result is correct....?

I think it is related with: #197

When I mark option "Use Experimental File Format" in Advanced tab then I have results similar to these one which you mentioned as 3.17.1
