In this case it was an external RNA that had been registered with an extraction date that was the ""latest"" date. Normally, external RNA doesn't have any extraction date at all or their extraction date or longer back to not interfere with the latest local extraction date. The external RNA should of course not be considered at all for this functionality. " defect closed blocker Reggie v4.40.2 net.sf.basedb.reggie fixed
