Months of Apex Legends Bugs Were Caused By a Single Line of Code

Apex Legends developer Respawn Entertainment said a single line of flawed code associated with an assault rifle was responsible for numerous audio and graphics bugs that plagued players during the Battle Royale game’s 16th season. made it clear that

Players started reporting bugs shortly after the start of Season 16. This is after noticing the lack of rifle sounds, Phantom he particle effects, and the disappearance of grenades that do the right amount of damage to nearby enemies but fail to detonate. The bug didn’t occur in playtesting, but after preliminary research, the most likely cause of the missing effect was narrowed down to a limitation in how the game’s servers parsed the effect.

If many players were running around with his Nemesis rifle uncharged, Stop His Particles His command onslaught was overwhelming the server, causing it to lose its effectiveness.
