Autocreation on payment fails

[Kirill]

We're launching a new product line that uses the same provisioning module as some existing ones. So... We added new servers:

Also created server groups for new products and added servers into them:

In the "Module Settings" tab we selected the specific servers group for provisioning and selected "Automatically setup the product as soon as the first payment is received":

However, when the first payment is received, this is what we get in the log:

Module Create Failed - Service ID: **** - Error: No server!

Is it me doing something wrong or is it a bug?

P.S. If I force "active" flag to 1 directly in the database for those servers, it works fine. But it's kinda weird way of solving the issue, imho.
