Can't move in y_airport

[anicole]

Hi guys,

My bot has a problem that he can't move in y_airport. I wanna leave y_airport. It appears "Cannot calculate a route from y_airport (143 40) to y_airport(143 39).
But I've updated the .fld and portals by "y_airport 143 16 yuno 53 214".

Can anyone tell me where I should check?

Check your tables/portals.txt for valid portals.

Thanks.
I solved it. The problem is on y_airport.fld. Mine is the old version.
Update it and it works.
