FOSS gamedev and creative worlds

I get the following messages in my log file:

Irrlicht log: Could not load texture:
Irrlicht log: Could not load texture:
Irrlicht log: Could not load texture:
Irrlicht log: Could not load texture:

This only happens when I use my tutorial (viewtopic.php?f=9&t=10192&start=25), but not with anything else.

Does anyone here have a clue what could possibly cause these messages? It’s nothing to serious, because it seems only to affect the log files. But it is weird. And why are no file names after the colons? :(

Got the same and not only with your tuto

I don't see these in my log, using latest Minetest Git, latest Git of your tutorial game and your world 1.3.0.

Oh boy, this is weird … :-(
I got to check this with git, too.

Some PCs make a duplicate file that starts with "._". The files are corrupted, so Minetest can't read them. There's no serious consequense of having the extra files except lost space.
NOTE: The files are hidden. You must make Windows show hidden files. Also you can't find the files on Macs, you can't view hidden files.

Nope, none of my files in the tutorial begin with a period.

But make sure! Remember what I said: by default you can't view hidden files. Look at the log and see if the files start with ._ and if they do, Google how to show hidden files on your particular device (I dont know if you run Linux or Indows or Mac...). Also please copy and paste text from the debug.txt file and show us raw data on the error.
