simple solution to that, i reduced my patreon contribution to this game and put more to games that are more consistent. games like town of passion, the twist, where the heart is, etc. on the flip side, i completely stopped giving money to iccreations long ago.
if you don't feel like you are getting your money's worth, just don't contribute. you should treat this like anything else in life. how much are you OK with spending for entertainment, and how much of that should each individual thing of that budget get.
having said all that, if he is really that stressed out, maybe it's time to hire someone to help. im pretty sure his patreon brings in at least $15,000 a month, that's assuming most of his contributors only put in a few dollars just to see the news feed. there is definitely room for contract work. this will help him as much as it will help us.
