I've tested the editor and it works. Do you get this crash over time or instantly? Can you please send me your savegame files to [email protected]
For me it crashes after a little time (sometimes short like a few minutes, sometimes a little longer like 15 minutes) and it may or may not be related to what actions you're undertaking at the time (I haven't narrowed that down). Always crashes with an access violation if the editor is open.
To be fair, when the editor isn't open the game will still become unresponsive for me after about an hour or two, but it doesn't crash (for me).
(edit)-I just started a new strategy game so I don't have any saves, but I can probably have some relevant ones tomorrow.
