I've seen a problem like this on our Rails app (2.3.8, but the issue sounds the same). Basically, there are three ways to delay an action.
Also check if you have restarted your server after the bundle install. That could be a issue too...
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
