Nothing ~ i mentioned this before when people say the artist is "still working"
Unless he starts releasing a lot of pinups to fill the massive gap between art and code, then all the "im still working while the coder recovers" is just words, because it will never be proven that he worked on anything, since the coder will be always behind (assuming anything of it is real, because we know patreon devs are experts on making up excuses ~ since they have big fanbases, they know they will never be doubted by them)
The artist probably just finished the build art and chilled for several months
