Yes and No. Sometimes it will fire manually. Also, additional information: If I let the system sit there and try to execute the node, it will eventually start firing in about 2 second bursts with a break between bursts of 2-20 seconds.
It also doesn't affect every NERV every time. Sadly, I do have a lot of addons, so I can't 100% say it's MJ. I did donate some $ to MJ project last night. Lord knows I've used MJ more than enough to pay for it.
