With the Hydragon, it's only been recently that the breath attack stopped working for me. I'm able to switch the breath using Left control, but c no longer allows the breath to be used. I read that it's supposed to be the opposite for these controls, but for some reason that's never worked before.

Also, any dragons with R set as a roar never works. I've tried everything to see if it would do anything, but nothing is happening with that key. I saw someone post using Alt R, but that doesn't work either. Am I doing something wrong for both of these?
