I got off my horse very near to the server border to check out a bag. When I went to get back on nothing happened. When I tried putting the horse away it just made a 'thump' sound. We could push the horse around with another horse. We could hit the horse and it would react. We tried digging a little dirt from under the horse but that didn't fix it. I tried a reconnect. I tried completely closing the client and reloading. Nothing worked.
In desperation we killed the horse. This caused a clone of my character to suddenly appear near where I would have been sitting on the horse but the horses carcass disappeared. We could not damage this clone but any barter requests or prayers directed at the clone were instead sent to me. Very strange behaviour.
Do I need to contact a GM or something to hopefully get my horse replaced? Horses are a pretty damned rare commodity these days.
PS. I've got all this recorded if proof is required.
