Simulation Odometry Bug

[ProfessorAtomicManiac]

          I am unable to simulate this at all - odometry seems to be broken for some reason?

Can others vouch for the code being able to work?

Error at org.carlmontrobotics.subsystems.Drivetrain.getPose(Drivetrain.java:538): Unhandled exception: java.lang.NullPointerException: Cannot invoke "edu.wpi.first.math.kinematics.SwerveDriveOdometry.getPoseMeters()" because "this.odometry" is null
