Hi. I encountered this issue and was able to reproduce it 100% reliably with all mods disabled except this one, so I'm pretty sure it is the cause here. Hope you can fix it! 🙏🏻 Here are my findings from testing this (these tests and images were all done with only this mod using Lovely and Steamodded with all other mods disabled. Game was running from Steam on Windows 11):
The crash happens after buying a joker with the Perishable status in the shop and starting a new round. For some reason, this mod causes the counter for the perishable status to trigger to show a "nil" value. Also, the perishable badge is missing from the card; it is only possible to know it has the status from the explanation pop-up when hovering over the joker card.

Furthermore, disabling the mod mid-run doesn't solve the issue. Doing that makes the Perishable badge visible again but the crash still happens the same way, even in future shops on the same run! The bug only goes away after starting a new run. For example, in the image below, this mod was disabled and the badge appeared again, but the bug still happened after buying the joker and starting the next round (in this image specifically I already had other mods running again, but I was able to reproduce this behavior by having only this mod enabled and then disabling it).

- hm, I just had an idea to check if disabling the mod before starting the run and enabling it mid-run would also trigger the crash and missing badge 🤔 I didn't test that.
Misc. findings:
- If the joker with the perishable status is bought and you get stuck in the run because of the crash, it is possible to, after restarting the game and continuing the run from before the crash, sell the joker you just bought and then continue without the crash, allowing you to not lose the run completely (helpful in case anyone comes across this crash before a fix comes up 😅)
@DivvyCr let me know if I can help with something in case you can't reproduce this still 🙏🏻 I love this mod, thanks for making it!
