You're damn right, friend!
I've been trying to fix bugs, balance issues, and crashes for the last few days. I don't have my own testers, and this is an alpha version, which I clearly haven't tested enough.
The save issue is the hardest one right now, because I use Python classes to initialize characters.
And Renpy can't save such objects to its save files.
I'm trying to fix it, and I think I'll release a version with major bug fixes in a week or two.
Don't save the data in the characters then, you can store relationship info the same way you currently store stats and gold.
Any particular reason you have things set up that way? I haven't messed with Renpy to much but from what I know usually you just have a flags list/file that stores everything rather than splitting data between multiple things. I've been messing with doing a VN-like game in Godot and thats how I've been handling it there.
I already have 20 characters.
From the very beginning I really did it with the help of regular flags, like gold, health, and the main character's characteristics.
But then I decided to improve other characters, and as it usually happens, I ruined something extraneous (in our case, saving).
Will fix it.
UPD: Fixed in 0.1.3
