TTL check did
subSeconds(1) for some odd reason. Note: @tsteur there didn't seem to be an issue w/ the ttl check that happens before invalidating, so if that was the problem you were experiencing, I couldn't reproduce it.
@diosmosis worked for me 👍 . Was going to merge it but noticed a test is failing. Can you check out https://travis-ci.com/github/matomo-org/matomo/jobs/452063651#L846 and then merge it?
