Renpy Crash when you click the sort by "Unread" button

[Yomic]

Whenever you try to use the sort by unread function, renpy crashes with the following log:

I'm sorry, but an uncaught exception occurred.

While running game code:

Windows-10-10.0.22000 AMD64
Ren'Py 8.2.1.24030407
Test Encyclopedia 1.0
Thu Mar  7 12:26:44 2024

I have created a bare-bones test project to reproduce the issue using the same encyclopaedia setup I'm using for my main project. Test Encyclopedia.zip

The only additional code that is changed is in script.rpy and the new file enc_1.rpy to define an Encyclopaedia and entries.

I am using the most up to date version of renpy (8.2.1.24030407) and addon (3.1.0) as of this ticket. Let me know if you need more additional information.

Pretty sure I know the cause here. I'll try to land a fix this weekend.

Fixed in 3.2.0

Confirmed fixed on my end on the test project and my main project. Thanks for the quick update!
