Aye, I am sure it was upgraded, as I remove old addons and install new ones or updates manually. Force of habit.
Strangely enough, the error has not reappeared on any of my characters on any server since the initial time, and they all show upgraded to .14 on initial login, so I am keeping my fingers crossed here. Once the error was cleared by reloading, it did not show the splash screen on the character in question, but all seems well so far.
Checked for that paperclip, not finding it here, might be a Firefox thing. I used the Insert Image button on my prior post, and it went through the paces, but no dice. Ah, well, here's hoping!
