Not a big deal here, but almost worth a mention.
I have an "Entities card" which I'd like the icons to be green when good and red when bad. This was working fine until the recent update at which time they went to default.
Reloading YAMLs did not fix it, nor reloading HA
What did work was to edit the dashboard, then edit the card, and, even though there were no changes, saved the then and "done-ing" the dashboard edit.
