Ok, someone else gets that error too! I have no clue HOW to fix that myself, must be the custom font I'm using for some of the special symbols, but should hopefully get fixed during layout.
Let me know if you see anything that seems to be missing. I don't see anything on my end. The only special characters from a font should be Accuracy, Difficulty, the linked weapon symbol, and the action/phase symbols ( Phase (1), (3) Volley, etc).
