Hi, I have a bag with 14 seconds of lidar data and tf (_carla/ego_vehicle/lidar_ and _/tf_). I'm trying to do an offline_scan, but just one time I saw the map in rviz, all the other times it gives me "No map". In debug mode slam_toolbox prints many times:

[DEBUG] [1638535964.467017944]: MessageFilter [target=odom ]: Added message in frame ego_vehicle/lidar at time 35.097, count now 5

I use the standard launchfile with the basic configuration with just one change: base_frame: ego_vehicle/lidar`

Here's my bag file if you want to test it out: lidar_tf_14_sec.bag. To play the bag I use rosbag play file_name.bag --clock but also without _--clock_ doesn't work. It worked just a couple times, no idea way. I'm running ros noetic. Thank you
