The normal schedule is the one from patreon page faq. 2 months is the goal and may go a bit more depending on how the content is and how I feel about it.Please don't take this the wrong way, but you can only use the 'normal release schedule' promise so many times before it becomes meaningless. Especially as 2 out of your 4 updates (if my maths is correct) since base game was released have been delayed. What constitutes a normal release schedule?
And indeed, it's normal for people to get restless after delays. Which is why I don't comment too much about it and rather want to update and get back on it.
