Hello,
I had a problem until I updated my .Net Framework to something newer. I am not sure If I had an older one, but looking for the newest helped. Then I re-downloaded the assets just in case.
Below is not an issue. I had the same error that Mike had when he loaded his up.
However, I came across a “loading error” when I opened up the game:
Failed to load /Game/Levels/Level1_BuiltData.Level1_BuiltData Referenced by PersistentLevel
Does this matter or is there a way to fix it if it does?
