!! This license is in use on multiple domains...

Hi Folks.

When I go to manage my purchases at the Ellis site, one of my ExpressionEngine purchases shows up as being used at two domains.

!! This license is in use on multiple domains, please make sure each use is authorized (using Multiple Site Manager, for example).

One of them is my local development site where I do the actual work, and the other is the live site, where the local changes are pushed to.

Should I bother to give this a second thought or should I somehow rectify this. Surely I must be allowed to maintain a local in house copy running for development, no?

Thanks.
