I just realized, the thread title edit works differently in this verison of vBB.
After an edit, the original thread title is no longer visible on the top of the OP. So, if a typo in the thread title is corrected, we no longer know what the original typo was.
Yeah, I was noticing that, too, xash … probably just as well.
If you do want to restore the original title as the subtitle, you can edit the OP solely, after editing the thread title. I added a “II” to your OP, xash.
