To be fair he was dealing with a kidney stone that he first tried to pass on it's own but then had to get surgically removed. I do believe all of his games were delayed as a result. He could've just put this out as more of a heads i'm back but it's probably more like business as usual. idk I don't regularly check his posts and discord.
The kidney stones arc pretty much ended up being extremely suspicious.
Summed up, he got kidney stones, had them for about 2 months and also after telling people he had them, he went out to drink and have sex on his birthday, which pretty much is something you shouldn't do if you're suffering from a debilitating pain such as kidney stones.
Then, either the stone passes naturally or you get it removed, but you don't need to wait 2 MONTHS to do so, if you have such excruciating pain that renders you unable to work or hell, even do regular every day stuff normally, you don't wait it out ESPECIALLY since he already said on Discord that the stones were too big to pass them down naturally.
In short, the kidney stones arc is pretty sus however you want to see it.
