Quotes disappear

When I reply to someone, anything I quoted vanishes. It happens almost all the time, or all the time. I don’t remember.

I have to edit the post, and re-add the quotes. It’s been happening since I first started talking here, over a month ago.

I use Opera and W10, x64, both fully upgraded. I really don’t have issues with any other sites. As an IT guy, I suspect the problem is on the website’s side.

Thanks for your time.

I started having this issue as well. Sometimes I can edit back in, other times it will show up and then disappear again a few seconds later (no manual refreshing or interaction with the page.

Firefox Windows 10 fully updated.
