Ofc it is. Once you successfully make extractors generate server side maps based on up to date stuff, everything works fine, unless some models (usually WMOs) are really, really horribly broken. And I have seen that happening only with custom WMOs made by Mirror Mashine, not with retro ported ones.
Extractors won't work with files which aren't in listfile and are "encrypted". As simple as that.Using (updating) only part of files might get you into compatibility troubles and random server crashes (personal experience), at least in regards to vmaps.
Well, that error says all you need to know - extractors can't find some files. Do files listed in that error log exist, or not? Screenshot you have taken doesn't really show world/maps/azeroth/ folder.
Error tells you stuff like "could not find Azeroth_12_40.adt". Now tell me, is that file in your patch in world/maps/azeroth/ directory? No, it is not. I am kinda lost now, because Idk what is it you still don't understand. Files which are supposed to be there are not there. So either your WDT file, which marks which ADT tiles are supposed to be there, is incorrect/outdated, or you simply don't have whole map (there). Or you have renamed some ADTs and moved them to coords they are not supposed to be, while not remaking WDT. Or idk, there are many possibilities.But the main thing is that I have an impression that you have no idea what WDT file is and that you have never even created a new, custom map. Otherwise you would know what to do, even while you are just modifying an old map.
