It's baffling how his patreons seem to be a-okay when it comes to putting up with that...
Basically it's something along the lines of "Oh well, someone who didn't really want to support me, who only paid the minimum amount to get the build decided to leak it, so I might as well punish all the loyal supporters I actually have by holding back content I planned to add until a later patch."
When he dropped that announcement, I dropped my pledge. Because at that point, the dev lost me entirely, not to mention the dip in quality and content released.
