Description

The tests are failing locally, i'm not sure if this is just me or not though, this stems from the recent thumbnail caching

attempts to read cached thumbs are being made to \dev\null?

also not sure if this is just windows or not i'm just assuming it is

Expected Behavior

Tests should pass normally

Steps to Reproduce

1. on a windows system attempt to run the tests locally
