gz sim specific.sdf - run random world if present more than 1 about gz-sim HOT 4 OPEN

It's not clear to me what you're trying to do. Are you trying to run two different instances of Gazebo with two different worlds at the same time?

from gz-sim.

It is synthetic case only for bug demonstration.

I discovered the bug by accident. I worked a lot with the ros_gz launcher and launched different Gazebo maps. Somehow one of them did not unload (although it should have unloaded) from worlds and for a long time I could not understand why a random map began to open instead of the desired one.

So, the issue is more about accidentally running two instances of Gazebo because, in your example, the ros_gz launcher did not exit properly?

I believe it is about unpredictable behaviour (bug) of Gazebo. Because if i run gz sim specific.sdf i expect it should be launched regardless of what worlds were loaded before.
