Objects with missing sprite do not load at all.

[tylerandari13]

SuperTux Version

v0.6.3-1204-g3bb35a1c1

System Information

Linux 64-bit (i think)

Expected Behavior

Objects that have a missing sprite load with their default sprite. I believe this was a retrocompatibility measure to prevent the screen from getting spammed with missing textures.

Actual Behavior

Objects that have a missing sprite do not load at all.

Steps To Reproduce Actual Behavior

• Make a level with an object that has a missing texture. (by removing an image, or setting the image link to be spam in the txt file)
• Dont forget to save.
• Restart the game and open the level again. If done correctly the object shouldn't be in the sector at all, and if you set the image file back to a valid image and restart the game the object will reappear.

Additional Information

I was playing some playtester levels and I noticed a lantern that's supposed to spawn isn't spawning because it used a sprite that was not yet in the game, and because of the compatibility measure mentioned above i was very confused when no lantern spawned at all. I also mentioned this issue here.
