I haven't seen a full patrol for a very long time. I've only seen 1 pillager patrol, and it's not the patrol captain. I think I've only seen two, maybe three since 1.19 update.
I've tried excavating at least 5 trail ruins and all have the top part showing, but then stone. Thought maybe a bug so now I'm checking here.
Update: dug down until I reached something, and this one trail ruin I'm at, dug 10 stone blocks down and found terracotta.
It works.
I'm having a similar issue (ver 1.19). Instead of exiting the nether, it happens when I enter the nether. The loading screen freezes, so I close my game. When I go back in, my location is the same as when in the overworld, but in the nether (My portal is at ~6,500, ~60, and that is my location when I load my world and spawned in the nether). I've tried reducing my chunk radius, which was working until it happened again. I went from 18 chunk radius to 6.
It's still doing it, both single player, multiplayer, and realms.
