EDIT : There was a problem with this update where you couldn't exit your ship properly. That's all fixed now.
I just uploaded a new build of 1.1.4 with the following fixes:
* Major bugfix to bounding sphere calculation which was using the wrong worldspace. This will fix the problem where you arrive at an asteroid but can't shoot anything, can't land, the enemies never fire, and other catastrophic errors.
* Fixed a multithreading-related crash
* Fixed a UI problem with the ship editor. Now your chosen tileset will still be applied while you add new grid squares.
Thanks all for your help tracking down these serious issues! 1.1.4 is still in beta so please let me know if you find others!
