I have the test image running with fix thumbnails running every hour. I disabled the script that I have been running to do this same function. It will take some time for my other scripts to grab some YT videos that will need their thumbs fixed. I'll let you know.
This brings up another question. Each time I restart olivetin I have to go back in a restart any recurring tasks and associate the correct healthchecks.io links? Today it is the TWIT guide and fixthumbnails that are recurring.
