Console is outputting the wrong file path and line number with editor scripts

2786391--201863--78081-2016-09-12-11-59-56-unity-personal-64bit-test2unit.png
It has the class and method name correct, so I know where it’s coming from, but the the bit on the right (Assets/Scripts/Util.cs:39) is completely wrong.
There are no errors in Util.cs.
I’m using Unity 5.3.5. I’ve had this problem for quite a while, it’s very annoying.

Please help
