This should exempt any zones that are not ready;
Code:
UPDATE zone_points set x='999999',y='999999', z='999999' where x='0' and y='0' and z='0';
Since the query looks for only the ones that have x,y, and z with 0's, it will only fill in the ones that are not fixed. So far, it looks to be working.
For anyone just tuning in to this thread , Leika has already posted pre-Kunark fixes in the first part of this thread.
