Just update it, ren'py keeps it's saves in the computer's AppData directory so you'll always have access to them. The only time using old saves doesn't work is if the creator says old saves won't work because of significant changes/reworks. This is usually a rare occurrence.

There's an issue with Mikosh where the event where some people try to capture her starts up even if you're meeting her for the first time. And it replays randomly when you visit the outlet hub even if you've seen it before.
I tried starting a new game since my old game I had been playing on since version 0.4ish figuring maybe it was an old save bug, but the first time I visited the outlet hub, the event fired off again. I was still early in the game, when you try to find Asmedia in her room but it says she's not there and to try the town square. Version 0.73 btw.
Added note: It seems to occur if you visit the Outlet in the evening.
Storyline-wise it makes the most sense. Censorship dictates the default is "landlady" and "tenant" and "co-tenants" or "friends" or whatever between MC and Sky, but it's fairly clear they're mother and children with Klara and siblings. One could argue step-siblings, or foster mother and wards if you like and it would still make sense plot wise. Landlady and tenant is very amusing though, considering the reactions to the potential romantic interactions. Ch. 5 makes it pretty clear that the MC and Sky grew up in the same household though.
