at 9 minutes in the video shows an error – it says to save your game in the bench and restart to fix it – ive tried this for 10 minuted and the error persists. My error is identical to the videos so not sure if he did anything different – i even restarted unity to see if it worked?

This feature worked for all the other save data bits – even when i remove the wall jumping bits from the save data script, the console will throw the same error – not sure what happened

The DebugLog – “worked” doesnt play – neither does the “file doesnt exist”

Only thing I can tell you here is that if the Debug.Log doesn’t play, it means that LoadPlayerData() is not firing at all.

ah yes i figured this out yesterday – it was a formatting issue:

had to keep my writer and readers for transforming player position and loading scene at the bottom – not before anything else
