Reference Workbook Save Fail (mydocuments)

I have one workbook that im running a userform. From this form i open another form that is contained in another previous opened workbook. On this second form i can update cell values in the second workbook. During this updating macro i am saving the workbook. using thisworkbook.save. Though For some reason when it hits this line. It must be doing a Save As and putting the workbook in mydocuments. There is nowhere in the code that references mydocuments.

Though if i open the workbook on its own (withough calling from another workbook) and load the userform the code runs fine and saves the workbook in its correct place.
