[solved] I'm seeding but the peers are stuck at 99%

[Faldrian]

Hi!

I have a torrent-file which had ~20 leechers but nobody had the content. I knew where the exact content could be found and copied the files in the directory, which transmission was going to download to.
Then I hit the "Verify local data" and it popped right up to 100% and started seeding.

After some time everyone of the 20 leechers were at 99% - but are not leeching from me anymore. No one else is at 100% and seeding.
There is no upload limit for the torrent file and ratio limit is also turned off.

Any suggestions, why the other torrent-clients are not completing the torrent / downloading the "last" part or so?

I'm using Transmission 2.22 (12099) on Gentoo Linux with the GTK Frontend.

It verifies to 100% and still doesn't upload the last part to the peers - nothing changes.
The torrent consists of a folder with 19 files in it, some binary, some textfiles.

update
Seems that the problem solved itself somehow. But I still wonder why this 99% issue lasted for 2 days.
