I did the mini update today, thought I had some issues with gamma and shit, so I reset the folder by deleting it. Now I cannot hold my breath anymore.

I looked in the XML file: Michael.dayz_preset_User.xml, and there isn't even a hold breath button assigned.

I looked in the other file to see if I could manually add it, and there is a

<input name="UAHoldBreath" loc="" />

So I went to the other file and wrote:

<input name="UAHoldBreath">
    <btn name="kLControl" />
</input>

but that simply doesn't work. First off, if I don't set it to read only, it gets removed. But even if I do, it doesn't do anything for me in the game.
All other key binds I changed work fine, and since I did that, I though I'd perhaps made a mistake so I reset them again and reloaded the game, to find the hold breath still not a function in the key binds file.

I wonder if somehow it is using the old file to read the control for hold breath from, which in my case, doesn't have the keybinds in it anymore, just some visual settings.
