This happens on old saves, it seems.
Also some bugfixes here:
You must be registered to see the links
The bugfixes are old you can find them on your discord channel and your release is newer normal you as player think a producer release a bugfixed version and not a version with bugs and give the bugfix later out.
When a old save is for you a save from 0.56.75 then yes !!!
Your bugfixes don`t help !!!
For example:

And normal a producer should make a game secure that it runs by a update.
It can`t be that we as player have to start over and over again.
At a point you as producer should aso learn how a save works from version to version or when the version number between are over 10 or 20.
So that maybe a old save get a automatic update to a working save.
I tried first to play a old save further and have seen the different and started then new. When you take only the card numbers. Between the 0.40 and 0.50 have the same cards a difference between 20. The number 20 here have in the old version 40. The number 1-20 I haven`t get and when you play a game new normal should be that you can find the lower numbers so this is a part you can only wunder.
Aso when it is a Patreon version why no from them get the bugs and reported them have`t they played your game or what?
It was released 18.10.2024 when I see it correct so a lot of time to get bug reports from your Patreons.
