NL skips downloading missing tiles for levels with preview text

[Simon]

CE 1.1.1

This works:

• Have a level without preview text, but with missing tiles.
  
• Go to its preview screen. The level image contains some checkered question marks.
  
• Attempt to start the level.
  
• NL asks you: Missing tiles, do you want to download the tiles?
  
• Click: Yes.
  
• NL downloads the tiles.
  
• We're back in the preview screen, and the level previews normally.
  

This is a bug:

• Have a level with preview text, but with missing tiles.
  
• Go to its preview screen. The level image contains some checkered question marks.
  
• Attempt to start the level.
  
• NL proceeds to the separate screen that prints the preview text without the level preview image. We can read the custom text.
  
• Click again.
  
• We're playing the level and see lots of checkerboarded question marks instead of the terrain.
  

Expected instead: After step 3 of the failure, NL prompts us to download the missing tiles. You can download the tiles reasonably around step 3, 4, 5, but definitely before step 6 of the failure.

Throughout all this, I have activated the online features in the options.

Example level with preview text and downloadable tiles is Re-Enlistment by Giga. It's in the Level of the Year 2025 pack.
