I just downloaded 1.11 for switch as it just became available and I loaded up my world that I have been using for months. I have a village beside my house and I was under the impression that after the update they would have changed to the new villagers (as is stated in the change log) however when I arrived at the village, all villagers had the old brown farmer skin despite the fact not all of them were farmers (one was a cleric for example) and they had a visible badge for their trade level despite being the old textures. I then tried to trade as I usually would and nothing would happen. Not even a bit of loading lag or anything, just nothing happened and the villagers would walk around like I’m not clicking on them. I went and found a new villager for the world so it would be newly generated. All the villagers there work fine and are able to trade so I think the problem is just with the old ones in already existing worlds.
