You can see in my screenshot that there is NO RABBIT there, unfortunately there is nothing left to find and the quest cannot be completed
Ok...
Unfortunately I can't use Discord and only have this opportunity to discuss it, I'm sorry.
Of course I didn't read about the Medusa pois beforehand. Personally, I find this really exaggerated and in my opinion that takes away a lot of the appeal of the mod.
I have now tried your fort a third and a fourth time and could not complete it both times. This time it was at a different point.
I play a lot of mods and never had such problems with the prefabs! Everything always worked with the quest. But here in the Wild West, unfortunately, it doesn't work for me at all. It's a shame, I really liked the mod, but now I'm constantly stuck on these quests that I can't finish and that's annoying.
It's a shame, but there's probably nothing you can do about it.
