Computer shut down in middle of exam

So I took my exam on Friday (Oct 7th) and during the 6th block with 20 minutes left my computer randomly shut down and started rebooting on its own. The prometric people were able to log back in and the test picked back up where it left off and I was able to finish the rest of the exam without issues. From what I remember it seemed like my answers weren't deleted or anything but now I'm just paranoid that maybe the results will be messed up or my answers didn't go through, especially since this exam is a retake :\

I'm wondering if I need to report this event and if so, how do I go about it? Is it a good idea and does anyone have experience with this??
