As I have said in the other thread.
Is the problem at the point of scan in the system or is it in the selling.
If it is in the point of scan, then it is not logged on the servers and FD would have no way of telling if you did or did not scan the system and so cannot retro credit you.
If this is the case, then a lot of your scans could be pointless
A big question as to whether it is worth continuing exploring whilst this bug is around ?
for some afai undertand it. All the scan data is around even after selling. Just the "first discovered" tag is missing. That would heavily point towards bug is at the selling stage....
