This is probably a well-known glitch to many players, but I just would like to inform the developers.
Basically, what the glitch does is when you go in to morph with someone else, your page crashes after morphing. You then have to force-quit the game and log back in. I know lots of players have experienced this. This bug usually occurs when you're in a crowded realm, or have experienced lag before entering the tent. So far, I haven't seen anywhere else where the page crashes in the game. Hope this helped, let me know if you need more specific information.
