Hi there!
I try to make a fix with the new Book version. Please try now the 4.1.8.
But I have to say, I tested it with the Mog Sample project, with all his plugins, and I didn't manage to replicate the error.
I see that you use the MOG Battle Hud 1.0. The sample project I tried, has version 1.1. So I believe it is best if you update your Mog plugins.
