Someone private messaged me. I responded that same day with a page-long response. That message didn't go through.
So, I tried it again a few days later when I noticed that my response was gone. I spent another hour or so writing a response and guess what? That disappeared too! After I clicked "Message" to send my response, the messaging interface said something like "saving..." and a wheel spinning. But, it kept spinning and spinning and spinning. I don't know what happened afterward because I forgot about it. I must have closed the web page by accident.
Just to let you know, the messaging system doesn't like me and it's messing with my mind.
