Crash after reporting target

[fbenti]

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

could be related to: #209

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

[fbenti]

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
