I get that too! D:
Ugh, I hope it doesn't start happening a lot. I need to use tab and moveobject for the comps im in.
For me, it's usually if I get too close to an item. For example, If I'm trying to take a picture like this: http://2.bp.blogspot.com/_sAjF9ZXDeHM/TTkDcvyghkI/AAAAAAAAAOM/0LdnIECZE3Y/s1600/Screenshot-230.jpg AND THE BED WILL KEEP DISAPPEARING! And that wasn't even with more objects -_-
How dare your venue get in the way of the background! Maybe it's an over-enthusiastic "hide objects" function.
Yea, everytime I get close with tab it gets all weird like.I deleted my caches. Hoepfully that works, but it does seem like hide objects over doing it a little. May have to play around with my game setting again. >_<
