N-line not taking priority over c-line

strange problem since re-install of my vu+ VIX image running cccam 2.13 or 2.2.1, i have one n-line (local lan to debian server) and 4 c-lines from peers , the n-line always took priority, now the n-line takes priority when you re-start cccam but on a channel change it jumps to a c-line share, the n line is first in list? any suggestions why? is it to do with access times or something?

cool , still seems to be doing it on 2.1.3 though or should i remove 2.2.1 as they conflict if both installed??
