I hear there is a glitch that makes Shadowmere die like a real horse. We have all the patches, I checked today and no download came up for the patches. Shadowmere has been dead for a while and has not respawned. What gives?

Your bro still camping his grave?

No he left the area and had been questing around and all that. But he came back to the scene of the crime today and still no Shadowmere.

It fits that the one npc you don't want to die is the one that is glitched.

Interesting... are you on console or pc?
