i just spend 2 fucking hours working and charting for my custom song just for this game to crash and delete my progess. Now i actually wish you all woulda used our money for drugs
The FNF versions before v0.3 have better autosave features. When your game crashes before the v0.3 update, all you do is go to the "Song" tab on click on autosave.
I got an idea for you. If you go to Metadata under the Window tab, there should be a Save Chart and Save Metadata button. Once you click on both of those buttons, your whole song should be back to where you last saved.
