Walking on Mountains with Athleticism costs 2 AP when at 1 AP remaining

A bit of an unwieldy title, but yeah.

With Athleticism, moving on Mountain terrain normally only costs 1 AP instead of 2. However, if I move on a Mountain tile when I only have 1 total AP remaining, 2 AP are consumed and my character goes to -1 AP.

I suspect this might happen with Water tiles too, but idk

There's a working fix for this in the next patch.
