[Is there a way to find items on the map? My horse simply ran away.]

My horse was seen four sims away by my roommate and the house appears normal again. Is there a way to find my items on the map?

[lost item]

There was a region restart on my estate owned land last night somewhere around 2 and 4 slt. When I reloged I was sent to a safe hub where I waited for a very long time and finally logged out. When I relogged about an hour later I went home and paid not much attention to the home, as the part of the home I was in was untouched and remains so.  When I logged in around 8 slt I returned and noticed that my horse had gone missing and minutes later that many of my prims on my home had gone transparent though they still exist. Even still some of my items in the home have vanished totally. Please help?
