This isn't an issue with the addon. If you have multiple addons that manipulate the cam view this may not work because this also manipulated cam view. Thirdperson scripts, Lightabers, said addon all do the following. So you need to disabled them to be able to do this.. Sorry just how gmod is made. I have no idea i there is a fix to this problem other then my soluation of disabling the other addons.
