It’s not really a bug, but you’re right about it being incorrect grammar.
I am
You are
He/she/it is
We are
You are
They are
In this case, we’re talking about it (the action). So it should be action is or actions are. I myself would prefer All of the actions are allowed instead of Every action is allowed. Every actions are allowed sounds pretty strange to me.
I’m not 100% sure about English grammar, so I might in fact be completely wrong.
Well, my English isn’t perfect, so I’m also not sure about that.
But if I would come to choose between these two “forms”, I would pick the All of the actions are allowed as well.
By the way, I have moved the screenshots to ImageShack, so you should see them now.
