I'm terribly sorry but I've deleted your comment by mistake while trying to delete mine, It was about that after_load thing.
I sent a message to the staff to restore it, unless you're okay with reposting it.
No worries! Here you go!
label after_load():
$ renpy.block_rollback()
python:
if _version == "0.20230507":
for x in some_list:
if not hasattr(x, "new_attribute"):
x.new_attribute = False
return
Thanks, I'll have to see how i can use that considering the main story event will take place during specific days, this is why retro compatible saves feel hard to work on here
I hope it works well for you and makes saves go over!
