Maybe Oleo can give an explanation?

I was seeding an 8GB file of which i uploaded 6GB.

I then pushed the torrent to 'ended' (i wanted to reboot)

After the reboot i the pushed the same torrent again to
seeding. Now it claims it has only uploaded 4GB.

I am using the latest version of 'transmission' from May 18
on a wl500g premium.

Nog a big deal, but is this a bug?
