Search and Replace only works to a point

[LxQ]

I did a Search and Replace on a range of cells from row 29 to 52. The search and replace worked up to row 35 only. Even if I do a simple find, it cannot find anything past row 35, even though when I look into the cell, what I search for is there. The partial string I'm searching for is: ")")

I think the problem is that after row 35 the formula in the cells is over 1000 characters long..
