Ddnet Texture Packs

In maps like "Sunny Side Up" or "2 Days to Vacation," the screen can become a mess of hook lines and projectiles. Many texture packs simplify the graphics. They remove unnecessary shading and make hook lines thin and bright, allowing you to see tee (your character) behind the effects.

This means your entities.png is outdated. The game is looking for a specific tile index that isn't there. Find an updated version of the pack for your DDNet client version. Ddnet Texture Packs
