Hi. There is a bug that I found and I fixed it.
That is when you have nested folders in a solution and you changed a file.
If you have in your solution more than one folders the files that are changed in the first folder are indicated this change and the build will increase the version.
But if you have a folder and inside that folder is another folder (or more) the files that are changed at the second (or deeper) folder are not indicate that change and therefore the build assumes no changes and the version does not increased.
I fixed this bug in the solution and now it works fine for me. I can send you the code or I can tell you where exactly you have to check for it, but I don't know what is the procedure I have to follow.
If you're interesting, please tell me how I can contact with you.
