Indeed, this would appear to be the case. I could not complete the tutorial either with the trainer activated. You also end up dying in the shack instead of just being injured and then shown the light. I initially thought I was missing something that I needed to find to get out of the cabin, heh.

i will check with the patched steam to see if this continues to occur. this doesn't occur with my version of the game.
