Interesting. I was able to reply to a PM From Eiryl. So, thinking it was fixed I then went to reply to one of the earlier PMs I needed to answer, and it ate my reply again. So it seems to be an issue with specific PMs? The hell? I have at least 2 PMs that are doing this. Maybe sending a fresh PM rather than replying will circumvent this.
I have this issue when receiving a PM from someone who didn't link a character to their account. I get an email notifying me that they PMd me, and the email contains the message, and my ffxiah PM inbox icon shows that there's a message, but it never appears in my ffxiah PM inbox.
Attempting to send a fresh PM directly results in the following;
That's a specific problem around a certain class of characters. You can send directly to their actual user account, and/or you can tell me who it is and I can fix the problem.
