Why are the "first Jedi Council" on Tython depicted with lightsabers? The force was discovered in 36,453 BBY and the Jedi order was formed around 25,783 BBY. But, modern Lightsabers (not protosabers) were not brought to the republic untill Naga Sadow's invasion of the Republic in 5,000 BBY.
I call lore shenanigans on you for using BBY for a game that happens before the Battle of Yavin! How can you track time based on something that has not happened yet? Obviously only a total non-Star Wars fan could make such a mistake.
