Due to the discovery of 3 game breaking bugs related to some of the new upgrades, that I discovered in the 11th hour, I am going to have to push patch 0.75 back a day.
2 bugs make the game impossibly easy, and one makes it plain impossible. They've been a nightmare to track down, but I think I've just been staring at the screen too long (my headache says yes), for too many days straight. I'll come at the problem with fresh eyes tomorrow, and hopefully get the update out in short order.
Sorry about the delay, but hopefully it's short! It's 90% done, and if I didn't spend the last 2 hours banging my head against the wall with these bugs, I'd be in the home stretch, writing up the final patch notes.
