Creating edges occasionally requires a server restart to activate

[Danielv123]

Steps to reproduce:

• Start 2 instances
• Create edge configuration to link them
• Observe that the edge does not create a link
• Restart the controller/the server/the host and the link will start working.

I am having this issue with my gridworld plugin where links are automatically created while exploring the world. The latest variation of the issue is that setting up a new link when leaving one instance deactivates other links on the instance you are leaving until it or the controller is restarted.

I am not really sure where to start debugging this, except looking into what happens when applyActiveEdges is called and what it sends to the instance to cause issues.
