I noticed that download and generation stats on model cards do not update for more than a day now. It seems to be the case for all models, but it's most noticeable for new published models staying at zero downloads/generations even though other users posted images made with the model. I filed a ticket for this.
Another thing I noticed is that some of my images posted yesterday got unusual many reactions. Looking at the images feed ordered by most reactions and filtered for time period "day" the images were listed pretty high although there were other images with more reactions listed below them (see image below).
So there seems to be an issue with the order of the images in the feed with these settings. I also filed a ticket for that. Will update this article if I learn something new.
Edit: Looking at the articles section, stats for article views also do not seems to update.
Edit2: I just noticed most of the images I published in a showcase post about 2 hours ago lost all of the reactions, maybe this is related to the other issues.
Update (15th of June 05:30 pm UTC): Missing reactions on images seem to have been restored for me. Also the incorrect order of images in "most reactions of the day" can be found in known issues now: https://civitai.red/issues?id=42
