Okay true, but the house glory issue was also happening on the regular client. From what I've seen, I think something about the hitbox is off, because the mouse is directly where is should be, but it says walk in the top left corner instead of edgeville. Maybe a failsafe is needed where the camera or the mouse moves around.
What should I report to the devs? I don't know what elements of your code is getting messed up by the mirror client, I just know that the script gets stuck.
