I think we already have a fix queued for this, no?

It looks like I fixed this in "Don't duplicate events from the final
event log in the TCG2 log" rather than a separate patch - I'm fine
merging this, based on Jarkko's preferences.

Right! OK, I squashed just the fix to the earlier patch. Master and
next are updated. Can you take a peek of [1] and see if it looks
