Just downloaded the update today, and I'm getting the same error as Nameless. Please update the zip.
Otherwise, this file is amazing! I had now idea that the sweat function was connected to her breathing counter. Now that I can change that, I can fuck the model and have her sweat while doing so. Great Mod Stuntcock! :)
If you're using a Character Folder (or loading the charcode manually by copy-pasting it into the textbox) then it ought to work fine. In that case, we're probably looking at a mod interaction -- there's something else which is pre-empting or modifying the game's handling of an incoming charcode. Please create a Help thread or send a PM so that we can investigate the problem.
