This has been happening to me for a while on a server, the connector would work once we'd place it but stop after a while. This issue has been happening for a while.
This Modpack does not have any other mods that mess with FE Other Than CC&A.

Reproduction Steps
Placed the large / regular connectors to a alternator
Connect them all you are supposed to do to another connector that is connected to something.
Set Push / Pull whatever direction you want.
And You're Done. Trains do not affect this, this was just the only example I had but it has been happening for other stuff too.
Expected Result
after 5 - 10 Minutes the connectors will stop transfering power.
