That's the reason why IPS removed rules from their marketplace. People get themselves into trouble and neither IPS nor myself can really do anything about it. That particular issue may be a bug "somewhere", but it is not in the IPS core, and I verified that it is not in the Rules application itself, so it is within the rules configuration on the client site. That is a configuration that nobody maintains except for the client themselves. Not sure exactly how to troubleshoot that for them without being able to reproduce it on my end.
But packaging a new version of rules and calling it a maintenance release is not going to solve that issue for them.
