Code:
map.ini mapmagicitem.ini ini/tme/yourmapid.tme region.ini gamemap.ini scene.ini weather.ini gamemap.ini actionmap3deffect.ini ani/yourmap.ani
^ all these files and more can have something in them that could cause that
and of course the dmap files but they are too big to bother with.
i would look in the
region.ini scene.ini map.ini actionmap3deffect.ini and mapmagicitem.ini first
search for anything pertaining to your old map and edit remove or replace it with the items from your new map
(maybe in your case compare the public ones to yours and see what is different)
and like soulnecturn said lol you should make sure ur server and client are running the same files
