Custom LL cards no longer load/work with 2020.12.2?

Not sure if a bug or not, I just updated to 2020.12.2 a few hours ago…

I just tried adding some custom lovelace cards (manually and with hacs) and none of them show up.

I just get a red card with in it:

No card type configured
- type: 'custom:xiaomi-vacuum-card'
  entity: vacuum.xiaomi_vacuum_cleaner

My old previously installed custom cars are still working however?

Weird. See any errors in your browser console (google for how to open it)?

Does this help?

It’s acting like the mod is not installed. But it is.

Looks like you’re just having a problem with configuring it. Remove the dash at the start, and unindent everything inside of your card config.

Bah… you are absolutely correct! Thank you!
