Hi Everyone!
It seems to me that the file is where it supposed to be, yet cannot be found by the BuildPatchTool.
Am I missing something?
Thanks in advance for the help 
Ok, it seems that there was a folder in BuildPatchTool with a previous game build, deleted it and that seems to solve the issue. Not sure if that was the solution but that was the only thing that stand out if someone has a similar issue.
