Movement problem in EB 0.8

[Sygrod]

Hi.
I just started to enjoy EB. I love that you really have to work at the battles, now. Even skirmishers are no pushovers anymore - quite the contrary.

I am playing Qart Hadastim and the danged Ptolemaioi decided to lay siege to an outlying fort in Kyrene with a solitary unit in it. I sent a relief army, but for the life of me can not get to the spot indicated by the arrow. No matter how gently I move the mouse in the area, I can't get a green broken circle to enable my unit to move there. I think that some of the units and cities have a 'sensitivity field' around them that may be a bit big. Is this anything that the EB team can tackle or is it hard coded?

Screen capture:

The relief army is just north of the spot and as indicated should be able to move adjacent to the ptolemaioi army and the fort.
