Wildcard subdomain is not being updated

[slaszt]

I've noticed that Bacon isn't updating the IP address for my account's wildcard subdomain A record. The domain updates fine so my keys must be working. Maybe my config.json isn't written correctly? I'd appreciate a look if possible.

{
  "domain": "example.com",
  "key": "[private]",
  "secretkey": "[private]",
  "subdomain": "*",
  "type": "A"
}
