Forums Bug Reports Log troubles and log reloading

I just updated from 6.2 to 6.21. I use a Messages window, and I log all queries and I have Reload logs: Both.

Now when I got a query from my friend: 12:00 <jd> Hey!! . I saw him fine in the Messages window. Then I right-clicked him and selected Query. The old logs was successfully loaded but I suddenly discovered that the message <jd> Hey!! was NOT in the reloaded logs!

I see now that the log is located in jd.Network.1.log (where I've never seen this 1.log before.)

What do I do? I cannot have this problem!
