While continuing work on my character select script, I encounter the weird issue of getting an empty debug screen at the end of the level and sometimes at the start, too. Do you have an idea what can cause this? This is pretty annoying, as it seems to reset a SaveData variable back to nil causing a onStart function to reset it to a default value instead of keeping the value it had before the level was ended.
Here's the screen I get:
and here is the corresponding code:
