are you sufficiently upgrading the goat enough to eat faster and move faster than the crows? and are you upgrading the rate at which grass spawns?
so the goat moves to a random corner and then just sits there? i haven't had that happen at all, and that hasn't been reported outside of you. if it's something that's consistent (like if you play the game again, does it happen again), do you think you could try and record it happening? i'd like to fix any potential edge case like that if i could, but you're the only person reporting that.
