Sorry, for the first point: when I use ":bd! NoOfBuffer", it is not listed yet. So bd is working well.

Okay, so what happens if you close all tabs and leave in just one window, wiping/deleting all buffers, verify that :buffers looks good, showing only the open window, and then save the session? Does the session file still have buffers that it shouldn't?

Basically, I'm trying to figure out whether there's a bug in buffer deletion, session creation or the autocommand mechanism, but to do that we need to create a simple example that demonstrates the problem and eliminates any potential human error.
