Has this been fixed? I am also struggling with restarting the global localization using version 2020.2.
I am teleporting the robot in Isaac Sim using dynamic control and it seems like the localization does not update as in the Isaac Sight Map View the robot is always in the same position and does not teleport when the robot teleports in Isaac Sim.
I have tried to reseed the particle in the ParticleFilterLocalization but it still does not work.
I have posted a similar question that might be related to this: Reset robot position with correct localization in navsim application - #3 by Hammad_M
