This time I think it bugged when I created some Points and copied it to all animations.
And now its making Spriter crashes when I try to open the project.
This time I noticed the points disappeared but where still in the hierarchy with different names, so I made a backup of the savefile.
But after I save the backup project, it get corrupted and causes spriter to crash.
Here is the project:

it have both the corrupted savefile and the backup.
