C2C War Dog
From my perspective it was more like "Start playing C2C, set up for game. ERROR you have chosen a Nation to Play! Continue or Exit?"
It's not a player that's made a mistake, it's the modder.
If the error is coming up its because something has been done that the code cannot consider safe to run and will likely cause a crash at some point if it is.
Yes, things have been tweaked before the error messages were reinstalled (properly) that have caused an environment where the dependency tags cannot be programmed as they once were. Yes that is frustrating and should be fixed (and the only one among us who was going to you've now offended because you're complaining that it's the error message itself that is at fault).
No, it cannot be ignored that it will cause a problem until it IS fixed in the code.
