So this seems to be a bug in international settings from what I can tell - for example the cooldown of the revolver is 0.53f, but your computer is making it 53.0! At least now I know what the bug is, and it is fixable. On the off hand that its an easy fix, would you mind trying this build and seeing if it works for you? No need for recording. https://www.dropbox.com/s/gya2v2ypd1f3a39/Duster%20INTtest.zip?dl=0
