I just sai... I have a similar issue in my project. Without any grass,it works fine without anyproblems, But after I use this groundeffect's adder + fix, some of my ADT's won't work anymore. I checked already so many parts of the ADT and event without Objects and co. , crash. Just when I replace all my textures from each chunck and 'repaint' it, it works.Maybe u have another problem by finding the groundeffectdoodads in your DBC, or maybe the same like my one always shout...We already recognized, there are just some little parts buggy on the maps; so sometimes u dont have to repaint everything. But we still try to find another way... repainting takes a lot of time, because the world and objects + npcs are already placed, to chance the highmap will cost a lot of time to replace everything.
It's definitely the grounddoodads. If you set your grounddoodads to low/zero (by config), it works in a lot of cases. However, I also know (in my own particular datas) of cases where the adts still crash DESPITE low ground doodads - as there are still some doodads set, I assume that it causes a complete mess with the id files.Schlumpf said not long ago to set the groundtexid in every chunk from 0xFFFFFF (-1) by hexediting. This however takes a lot of effort on many different adts
Try to delete all m2 and wmos. and aplly the mjollna's adt fixer
