Crash after reporting target

[fbenti]

After reporting the target vessel back to the operator, gazebo crashes unexpectedly but we can't understand why.

If you are using an rgbd camera for reporting targets, you'll need to update to the latest version that has the fix from https://github.com/osrf/mbzirc/pull/216. If you are switching streams when reporting targets, you'll need to make sure you have libignition-rendering6-ogre2-dev 6.5.1

I can actually see that the GameLogicPlugin.cc in its latest version on GitHub is different from our local version, even if we just reinstalled everything. How can we solve this problem?

[iche033]

It depends. If you're using docker, you can remove the current image (, e.g. docker rmi -f) and pull it again just to make sure you have the latest version.

If you're building from source, just checkout the main branch and git pull
