I couldn’t find anything else about this so sorry if this is already a topic.
When posting, sometimes a message will appear saying “Sorry, an error has occurred”. It usually takes about three tries to actually post. If it’s a reply, the post being replied to will have the wrong number of replies, usually three.
I don’t see any way to predict it, it happens randomly.
Unless we have specific repeatable steps to reproduce it, we cannot consider it a bug…
I identify with the issue; I’ve noticed it a few times on our instance in the last couple of days, since we upgraded to latest. I’ve also not noticed any kind of pattern to it, but I’ll keep an eye out now and see if I can provide more information.
