what do you mean? this game is not the kind to have half-baked sidequest that will be finished on a later update, unlike other games.(edit: maybe it happened before i found it but i dont remember a single instance of this on the updates that i have waited for, and i found it years ago)
the start of the game has a spot where it lets you finish all the ones from the starting part and after that the sidestuff(if any) gets added along with the main story in each update. THO maybe more will be added when the dev does version 1.0 and changes the start of the game to retcon/improve the story, along with the update to the visuals
