Simply said, the code is looking for "slash0.png" in the materials but there's no such file to be found there. If you make a copy of "slash.png" for example and rename it to "slash0.png" in the same materials directory, that fixes the issue. "slash0.png" MUST BE an empty transparent .png file.

Based on the quote above, I made a workaround fix to the missing texture overlay popping up for a split second every time you start the game by adding a transparent slash0.png file (in 1920x1080 resolution) in the materials folder of the addon. Although doing this fixes the missing texture, the addon still has some issues:

1. Since the missing texture issue has been fixed, players will now greet with dozens of screen blood overlays popping up for a split second after starting the game.
   
2. I'm not sure whether or not the change I made to the addon affects the multiplayer side of things.

If you want this fixed version of the addon, please let me know. I'll let others fix the issues above because I don't have any knowledge of LUA modding.
