Hello there.
I can't say that I am 100% certain that this is a bug, but some things just got me wondering if everything is really alright with this area.
I have visited Mt baratak and the ice priestess dungeon once every two days for about 10 days straight, some days without killing any of the low level mobs, but the spawn doesn't seem to develop fully in monster strength anyhow. Most of the visits have been over 48 hours apart as well. Of course I could just be unlucky, having someone clearing the place again and again...
BUT the reasons that got me wondering was due to the surrounding areas having spawns that have nothing but the strongest of Crag cats. (Whatever their names are now again). And overall the areas doesn't seem touched by anyone.
Who would make it up there and reset the spawn of the ice cave every other day without ever touching anything of the surrounding areas?
Anyhow, today I took a visit there again, and yet again the area is filled with some frozen corpses, and cold spirits. I walked up the the crate in the Mt Baratak Summit map, taking a dragon's eye item. Nothing more, I logged out and went offline for 8 hours.
I come back and check the crate again, seeing exactly the same items in the crate, and the dragon eye item missing in the slot where I took it from. Wouldn't the area reset for someone looting the place, or are containers not bound to mob spawn?
I've recently heard people complain about other areas around in Barovia seemingly not developing into full spawns, so I thought it might be worth sending a report about.
I did a debug command in the Mt Baratak Summit map.
If this IS an issue, I hope this will help you resolve it!
