I would look in Jamba-Follow and Jamba-Comms.
Ensure you have a follow message set, it is set to warn you when it breaks and the group it warns - usually "all", all toons belong to.

In Jamba-Comms you configure what is relayed and when.

Not sure if this will resolve your issue, it might be slightly different areas of Jamba.
But essentially check that follow is enabled, with the warning.
And then check that warnings are set to be passed along.
