Not sure if reptyr can help in this case. It's in the repos, so worth a
look:

How does someone "lose a terminal window"? Usually that kills any
running processes attached to the terminal.

If they literally can't find it, but there is no reason to think the
window has actually been destroyed, try ALT-TAB in each workspace. You
never know. And check for shells in the process list, make sure you
know what each of them is. Follow the process tree (check out pstree,
it should be installed by default) to find out what process owns exp1 -
you may find the shell that ran it.
