The very first executable line in L01game.pov is
#version 3.7;
So I don't know why your POVray code would run my code in the first place.
I never heard of 3.8 existing before now. The download page at
https://www.povray.org/download/
only mentions 3.7
Where do I get this 3.8??

Also the line in question is a text object which follows the syntax of 3.7 as
far as I know:
      text { ttf "crystal.ttf" substr(ColumnLabels, cidx, 1) 1,0 }
Is this now wrong?
