Turns out at the last minute I let a critical single-player bug slip through.
This release corrects it.
http://mythruna.com/forum/index.php?topic=566.0And I also added a scripting console, still only partially functional.
For would-be modders, you can run the game with -script on the command line and this will enable the console. Then when running in single player, you can execute the /script chat command and it will open the groovy console. Most of the environment is there from the other scripts but some important APIs are missing. Some stuff does work though.
