Is there any quest that will automatically failed if certain amount of time passed? Like if you get to day 50 without doing some early quest, you'll miss that part for good? Or you can pick up any quest any time you want? Sorry for asking.
No, you can't fail anything this way. You can pick quest anytime you want and finish them anytime you want. Some events can happen starting from the certain day, but it's up to the player when they will start them.
