So this happened to me tonight:
I joined a game that was already set up, and it seemed like the monster-player left before the game startet, but after he had picked his abilities. At stage 1 I had the abilities he had picked, then I evolved to stage 2 and suddenly the points he had assigned before the game were gone. I ended up as a Goliath with stage 2 health and model, but only 3 skillpoints in my abilities. Later I evolved to stage 3 and had 4 skillpoints available. Was kinda weird.
