Get In Losers*, We're Getting Off Nomad

I already asked about this before, but never got a reply. How do I get rid of this notification?

I neither want or need more than 1 instance.

And how do I scale down to 0 and back to 1 machine?

I simply run flyctl scale count 0 and then flyctl scale count 1, which immediately fails. With this message:

Error: there are no active machines for this app. Run fly deploy to create one and rerun this command

I tried runnin flyctl deploy this a couple of times, but every time I lose my machine settings, e.g. I have a machine with 512MB of RAM, scale down to 0, deploy, and it’s restarted on a machine with 256MB of RAM, which is not enough for startup and gets stuck until I scale the RAM back up manually.
