PR build working on 4 month old commit from merged branch

Hi all,

Reporting a new bug I am seeing:

Opened a new PR on a private repository today. The build failed, with a stack trace showing old code changed in recent commits.

I started a debug build, and this was the most recent commit from git log:

commit 4c857a5d5a523cc6caec2459619b67ecc52c1307
Author: egweber2 <ethangweber@gmail.com>
Date:   Wed Mar 11 16:42:05 2020 -0400

    ENH: integrate BulkDownloader into match_ids_joiner (#834)
    
    Co-authored-by: Ethan Weber <ethan.weber@farfetch.com>

However, here’s the last 2 commits I have locally (2 because I pushed a new commit to try forcing Travis to update):

commit 4ceda3599ed65859843ed41c3f3adee71f62515b (HEAD -> airflow-per-user, origin/airflow-per-user)
Author: Eric Fulmer <eric.r.fulmer@gmail.com>
Date:   Tue Jun 30 18:59:22 2020 -0400

    add type hints; squash

commit cff54e85162f4a9c3c845b390636fa32cd16c0ae
Author: Eric Fulmer <eric.r.fulmer@gmail.com>
Date:   Tue Jun 30 15:06:27 2020 -0400

    DEV: per-user utils folders in dev Airflow environment

Build URL: https://travis-ci.com/github/Farfetch/paidsearch/builds/173757605

I have tried squashing and force-pushing those two commits, but Travis is still “stuck” on that 4-month-old commit: https://travis-ci.com/github/Farfetch/paidsearch/builds/173759531

Any help is appreciated.

Edit: I have deleted all caches for this repo, but it’s still “stuck” on the commit from February.
