You can use Newgen with the updated World Editor, so that it'll have all the standard stuff (including hashtables), as well as all the additional features such as TESH and JassHelper.
When I double click on NewGen WE.exe it opens an older version of the editor.
I tried loading a map made with normal WE and it says it's an older version at least.
How do I open Newgen with the updated WE?
