I can't do it right now because all my struct/enum is in a mess.
When you add big structure you have to add others sub-structures before, things I've added after to "fix" the main structure. In IDA it doesn't matter because it's dynamic but by exporting it will written in order of creation, so it will fail in importing. Of course it's something you can change manually in the file. Also, there is some structs it will be impossible to import automatically like edict_s because it needs the entvars_s, but entvars_s needs edict_s too...
something you can add manually easily.
