Edit: I am engaging with FSRS Helper addon team on their github, you can ignore this.
I am a longtime user of True Retention, last updated in 2017.

This addon has been steadily working well for almost a decade now with no update.
Unfortunately today I found that part of it broke, a useful part.
The label “True Retention” in bold and all the table below it no longer show up. The parts above still show up, but not the table below.
This is a very useful table with easy to interpret info at a glance. I’d love to know if the author is still around and knows how to fix this. I tried disabling a few other addons, but it doesnt seem related.
Edit: I did some more testing. By reverting my addons to a prior version and updating the one by one, it seems that the most recent update to the FSRS Helper addon is causing this to break. What’s weird is that once I update and see the table is gone/broken, even if I disable FSRS helper, it does not restore the table. This is a bit beyond my understanding though.
