No, there’s nothing except the fact that the "laws of physics", ie. our models of nature, are eternally incomplete simplifications. All that’s going on is that our models have a prediction error and thus tell us we’ve failed to take something into account. Which is an utterly standard part of scientific progress. Papers will be written, hypotheses proposed, more evidence gathered, and after some number of years we’ll have a new, more complete theory of neutron star evolution and/or emission processes.
