I've noticed what is possibly an issue with the control panel related to the new balance changes.
The settings under Per Level Stat Multipliers, which show 1.0 by default, are being inserted into game.ini and are overriding the actual new default settings for tamed health/melee.
Or something like that? I'm not sure exactly, but neither 1.0 or 0 are resulting in the intended default settings, and I'm not sure what they should set at as it seems they have been changed again since the numbers noted above (0.15).
Hope this is helpful, cheers.
