fairly common in timber framed houses with brick outer leaf. Inner timber frame shrinks a bit as it dries, outer skin of bricks expands a little. There should be a gap under the window sill, and the window should be fixed back to the timber frame.... Otherwise sill gets pushed up.

Interesting diagnosis, but if this is case, fixing it will be tricky without removing the brick course under the cills, cutting them down by 10 to 15 mm and re-laying and sealing.
