Hi, I just posted a reply to a topic a few minutes ago, and the scrollbar on the right displays “Dec 2023” (the date of the previous post in the topic) instead of the actual date (Nov 2024).
A bit more confusing: my first post in the forum, dated today (Nov 2024), is now indicated as being posted in “Nov 21” 
That’s how dates are displayed in Discourse:
Nov 2021: November of the year 2021
Nov 21: 21st of November, 2024
I’ve seen a couple of times that the scrollbar doesn’t update properly until you do a hard refresh of the page, so I wouldn’t say this is totally uncommon.
Hi feslqualle, thanks for the info
