Update Zone Full Follows
Update zone full-follows packets are used to clear a zone (8x8x1 tiles space) from any modifications done to it prior, wiping any obj and loc changes in the process. This packet additionally sets the 'current zone pointer' to this zone, allowing one to follow it with any other zone payload packet, commonly used to synchronize the zone to the observer (restoring all the objs in it, loc changes and so on).
