1) Once the user has entered the main menu, there are situations where it's possible to answer questions in the Gun and SFX menu, and then hear the main menu's theme start from the beginning again.
2) If the user selects Grenade Mode for one of the players, it's possible to hear the grenade launching sound when firing somewhere on the Verification Screens that is not the target itself. This issue does not happen while the cursor is actually on the target's hitbox.
3) In automatic mode, it's not possible to fire bullets through the Reload button. This causes the Reload button to act like an excessively protective barrier.
4) In automatic mode, it's possible to "get free bullets" by lightly pulling a trigger. A bullet will still fire, and a shot sound will be heard. However, the bullet count will stay the same.
