Corrupt all backups when synfig hard crashes

Hi guys,

I’ve just persisted with this problem in the past but due to crashes I always make backups V1, V2, V3 ect. But if im changing an animation with the drawing tool, or it has even happened moving folders around in the app, it can somehow crash hard and when I go to load the latest file again it recrashes, this will also corrupt all my previous version save files with little to nothing in them. So I have to start from scratch. Running the latest version. Please help.
