Are you still having this issue? Please Reply haha! 

(no seriously, do reply if it is resolved.)

It's possible he was replying to a post in a deleted thread. Or had really bad internet connection at the time.

It's ok now. It was just that thread. Probably what Tanstaafl said.

Probably should mention the thread.

He could always message somebody or just make a new thread for each of his posts I guess? lol

 The latter is a bad idea if the former works though.
