You mean 2015, not 1995.

Most likely the previous result had a 'bad' error code. The number would have then been marked as available for a First time check again. Test with bad error codes are far less likely to match other exponents. There is a good reason for this. Someone else ran across this recently too. Rather than have a bad test make us miss a new Prime until we get to that range as a DC, those with 'bad' error codes are rerun soon.
