missing test on test log,strange ?

hi all,a while back I did a test [early 2017],mega failure, out of interest i tried to view this particular test & to see what happened to the car and there's no sign of it on my test logs,a slot must have been paid for as I issued a failure,cant help but think somethings a miss,anyone else had this ? I presume all the tests we do at whatever site we are working at ,are in our test logs? ps I left the place as they were a shower to say the least
