Getting Other Players Error Signs

[Bob_Rabbit]

This has happened to me on 4 seperate occassions. For example, imagine the person next to me is called jim and some error occurs for him in his game, my game will tab out onto the desktop on there it will have window open telling me that "Jim cannot change from stance 1 to stance 0". There is quite a bit more on the message than that but that was the part I remember.

I'll try get a screenshot of it the next time it happens.
