0 power thing was caused, I believe, by using powers from the social view, as opposed to main view. That's been fixed, in the new bugfixed version now available. I'd prefer not to leave any major bugs in the game at any point, or they'll get forgotten, and the gameplay will be weird due to their presence. Plus, I've got a bunch of free time now, because the entire world is being told to stay home for the next couple of months.
Anyway, thanks for the heads-up, let me know if you spot anything else.
