Thank you ; I didn't have think to this method. However, I already begun delete some of those I suspected and add them again one by one. For now, one reproduce my bug : DockingPortToggle. So in fact, even with your method, as it isn't a part which cause that, I wouldn't have find the bug like that. I'll continue to add the others one by one and test if another one cause the same bug ; but for now I would like to inform the developper of this mod. I said "would like" because when I shearch it in google, I don't find it. Maybe this folder was a part in the whole of an another mod. But for now I don't know what.
