Sorted out the missing 5th, it wasn't missing , just with something else!
Stuck now in the bottom right:
49a Blue community rejected order - grid entry is 6 letters and so far I have ???E?T
Possibly "order" is the defn ... sad = blue ???
44a John's holy map of France? That's right .... grid entry 5 letters ... FR?E? (F is dubious!) frier would fit the 2nd bit but can't see the John's holy map ??
Thanks for any help.
