I found the problem, and it happened that KPKP was incorrect, too (I am lazy, and reused part of the generator code in the verifier, too; the bug appeared in that common code). Fortunately, of 6 affected tablebases, only KPKP was on Bob's FTP site. And it's small one, and can be re-downloaded quickly enough, so problem is unpleasant but not very serious. Meanwhile, almost all 5-man 3+2 tablebases are on Bob's FTP site now - only 3 left. Hopefully I'll be able to generate remaining in a week or so. Eugene
