All the player images show, but not any of the standard ones from the resources folder. I'm guessing this has something to do with that resources folder inside the jar not being found. Maybe try re-downloading the game? the jar file may have gotten corrupt or something.
- What does the main menu look like? (I'm guessing missing question-mark button for the random player?)
- What about the sound? (I'm guessing the player talking voices are there, but no music or shuffling sounds?)
- Anything helpful in the text logs?
- What resolution are you playing the game at?
- What OS?
