The MVT extension takes uploaded geojson resources, breaks them into manifold tile files then uploads them to Amazon S3 where they are called when a resource preview is viewed. This process silently failed and had been broken for some time before I noticed it. This meant that newly uploaded geojson files were not properly previewing and updated geojson resources were using the previous copy of the data for the purposes of the preview (note downloading the resource still got you the latest version).
This happened due to a change in upstream package requirements for the MVT extension.
Creating this ticket after the fact.
