There was a tiny 25 MB patch to update from 1.0.86 to 1.0.87.
Some abilities have been removed (Field Medic, Battle Magic, Defensive Magic, Summoning Magic, Slayer). Abilities also require more than one ability point to increase.
Sourcery does nothing until a certain plot point, Aramintai, which probably isn't in the Alpha. Yes, it should be locked until then, but it is not currently.
