I believe terraform was trying to apply firewalls to droplet resources, and dependent resource was not available to handle it at the time. So some of the firewalls were applied randomly on each try.

Hey friend,

I believe this uses our firewall product, though it may use software firewall inside of a droplet. The first seems more likely. It may be good to cross post this to GitHub so that the maintainers can review it as well:

If you do get an answer elsewhere, please share it here so I can know how to help others who experience the same.
