Improved Silo filling Random Fields

[moreon]

I have just built a few of the new improved silos and they appear to be refilling random fields some distance away, is there anything I am not doing correctly?

[Jamdoggy]

If all the fields around the new silo are 'full', then this will happen. It should refill the nearest non-full wheatfield first...

I have a level 3 improved silo. this means it should refill 3 fields every 5 mins (approx).
Is this correct?
If so does it refill:-
1) the three nearest fields that are NEARLY full
2) the three fields with the lowest amount of wheat left
3) just randomly select any field that is not full.

A lvl 3 imp silo refills the closest non-full field with 3.

[Ramshill]

3 what?

[SmurfAsH]

3 wheat

The imp silo still only fills one field at a time, a lvl 3 will fill with 3 wheat at a time, with a production cycle of 4 mins (plus travel) as opposed to a regular silo with production time of 12mins (so the imp silo is 3x faster). It will travel to the nearest field that is not full.
