Nevada, I will say again that I do not think you did anything wrong. And anyone who is giving you grief about this situation is either a friend of the L in your OP, or is just out to get you for some reason.
You can't go in AFTER your third had a conversation with the L. That would look bad all around and would possibly piss off the L and/or cause him to disappear as you said.
My only thought is what I posted before: If you had IMMEDIATELY come across with fist raised and said something about Intentional right then and there, maybe he would have gone with it. Maybe not, but at least your critics would be silenced (as they should be anyway for crying out loud).
It's one of those situations where some people (like deranged, psychotic assignors) blame you for something that your P screwed up because "You should be able to take care of business in your games". Not that that ever happened to me.
Water under the bridge.
