When I try to use a /fill command or any other command on a marketplace map such as City Life 2 or Avon my game crashes and kicks me out to the Xbox Live Dashboard on Xbox One S. I believe it has something to do with the updates not applying automatically to your downloaded marketplace templates. Is there anything you can do? Here is a video recorded from my PC. It's 1:25 just about but it showcases all you need to know. Here's a link to the reddit regarding the same issue. https://www.reddit.com/r/Minecraft/comments/kge26p/city_life_2_is_broken/
