The bug

/place command sometimes doesn't check whether the position is reasonable, thus sometimes crashes game.

How to reproduce:

1. create a new default world (not a super-flat world)
2. then

• run /execute positioned 1000000 1000000 1000000 run place feature minecraft:acacia
  • returns That position is not loaded
• run /execute positioned 1000000 1000000 1000000 run place template minecraft:ancient_city/city_center/walls/left
  • returns That position is not loaded
• run /execute positioned 40000000 0 0 run place structure minecraft:mansion (must be mansion and out of world)
  • Throws an unhandled error
• run /execute positioned 1000000 1000000 1000000 run place jigsaw minecraft:ancient_city/walls minecraft:connect_wall 1
  • Return successful message
• run /execute positioned 40000000 0 0 run place jigsaw minecraft:ancient_city/walls minecraft:connect_wall 1
  • Game Crashes deobf_crash-2023-01-25_00.49.38-server.txt
