I don't know whether this should be posted here or in Tech Support, but the system has been bleeping things it shouldn't. This is already somewhat known, but I thought it important to start a topic in case it starts happening to others. This way they could add their examples, just in cast it helps to do so.
In the following thread, I'm having a heck of a time trying to help this person due to this issue, and I'm sure it's frustrating for him, too.
It appears that I'm going to have to start taking snapshots of every post/reply before actually trying to post it. This way, I can just post the snapshot in an edit if I have to, which will come in handy if the post is long.
I don't know what's caused the system to start doing this, but it's VERY annoying. It started a little over a month ago, and has been happening on both posts in the Community, as well as Private Messages.
