The AI rule violation detector detects rule violations in a game topic where, for example, violence against fictional characters is discussed and described. If the AI keeps doing this, it will flag every other message in the game, especially those with battle scenes and the like.
I also noticed that in private messages the "Inbox" tab doesn't work, and in the "Sent" tab it shows replies to my sent messages rather than my own messages.
What worked well against spam indeed requires more careful tuning for game topics. I updated the instructions for the AI and added context so it takes into account which subforum and topic the message is in. Let's see how it works; if needed, we'll fine-tune it further.
Regarding the private message user interface, I think the cause might be incomplete loading of that page's scripts. Currently there are no notifications if a web page or some required file is not fully loaded — only if you go into the browser console and check for errors. I'll try to add some protection so that if something fails to load and the site can detect it, it will say a reload is required. So a simple page reload should help, preferably with a one-time cache clear. If that doesn't help, we need more details — which browser, whether there are any errors. It's best to send a report via "Report a Problem" at the bottom of the site or in the menu under the avatar "Report a Problem" — that option passes along browser information.
