is ok in todays compile, .221 doesn't apply as valid segment file maybe .228 too (don't have checked this in detail) If you're using the newest makenl revision, there is an enhancement included, but there is still an open OS/2 bug, that throws exceptions since revision 3.2.7 (or around). The bug has been identified, a fix is delayed
By default, segment files from downlinks gets updated in a makenl run with current daynumber either way. But I don't know in detail if this happens also in the 'master' mode.
In a proposed bugfix revision 3.3.6 the search for segment files fails by other means, so therefor the proposed bugfix is set on hold for further investigations.
