‼ ‼ ‼ KNOW BUG: Thanks to @Spacedog , we discovered a critical bug which could make you lose all the datas from all plugins ( VAMStory, VAMStoryActions or VAMStoryDirector ).
This only happens if you create a story, actions or use director, putting the empty atom to "off" and saving the scene.
The scene will reload properly, but if you keep the atom off, and save the scene again, the hidden empties with the VAMStory plugins on them will lose all data.
This is due to the asynchronous loading of VAMS datas, only loaded when the atom is enabled.
I suggest not using atom on/off until the bug is fixed. I'll try to find a fix this week-end.
Sorry for the inconvenience.
