Saves randomly working

Hello all. I made a save system following a tutorial series by Tracey White ( . Everything works fine…randomly. Sometimes my “Best Time” and “Level Unlocked” saves to slot and sometimes not. When it saves, everything is perfect. But I don’t understand why the system does it randomly. Is there something wrong in my save pipeline? I attached both my save game slot and best time&level unlocked nodes for you to see. I’m desperate right now.

I found the problem. The thing is there’s an end game menu and before creating that widget I put “set game paused” and it prevents the game from saving most of the time. I think it’s according to whether the system manages to save before pausing and advancing the next level. So instead of set game paused I’ll make freezing the inputs or something like that.

So overall, system works.
