Download does not start if I register same .torrent 2nd time

[trtrmitya]

Hello!

I am using transmission-2.33 on FreeBSD-7.2 (compiled from FreeBSD ports).
I am trying to transfer a file from computer M1 to computer M2.
Both run the same software and are connected to the same switch (no ports are fi
ltered between them). They share the same settings.json (attached).

First I create torrent file:
transmission-create -o test.torrent some_test_file.tar
I do not specify tracker URL, because I rely on local peer discovery feature.
Then I copy some_test_file.tar into Transmission's Download/ folder and add torr
ent on computer M1:
transmission-remote -a test.torrent

M1 starts seeding.

Then I copy the same test.torrent to machine M2 and execute
transmission-remote -a test.torrent

Machine M2 finds peer M1 using Local Peer Discovery (I see multicast packets on
port 6771 using tcpdump) and downloads file.

Everything is OK till now.

After that I connect to M2 via Web interface and select "Trash Data and remove f
rom list". M2 deletes that torrent from list and removes file from disk.

After that I add the same torrent back on M2:
transmission-remote -a test.torrent

M2 does NOT download that torrent second time, everything stops:
M2 shows "downloading from 0 of 0 peers" indefinitely.

Why torrent is downloaded fine for the first time and download does not happen i
f I remove/add the same torrent back?

PS: I tried exactly the same scenario but using real torrent tracker announce URL, without relying on Local Peer Discovery feature.
I got the same result: successful download for the first time, and no download if I remove/register again the same torrent.

I am attaching my settings.json file:

Thanks in advance!

BTW, I sometimes see machine M1 in M2's peer list with lowercase "d" status: "We would download from this peer if they'd let us".

After few seconds, that peer disappears from peers list.

Why M1 does not let M2 to download?
