I've built a wall around our village on realms and lit up the inside of the perimeter and the top of the wall. The wall is five blocks high and one thick. I'm planning on setting up more farm lands and lay down slabs to try and fix this issue but it appears to be a bug. I thought raids and scouting parties can't spawn withing a village perimeter. I haven't lost any villagers thankfully but I am down to iron goloms. Again I believe this is a bug but my understanding my be limited. It's also on normal and is played over realms. Thanks a million and any advice is welcome. This is also on Xbox one edition and is up to date with the latest bug fix.
