The bug
/place structure command sometimes still doesn't check whether the position is reasonable.
MC-259355 is not fully fixed. Only /place jigsaw was fixed, while /place structure is still not fixed.
How to reproduce:
create a new default world
then
run /execute positioned 40000000 0 0 run place structure minecraft:ancient_city
✔ Fails and returns "That location is not loaded"run /execute positioned 40000000 0 0 run place structure minecraft:mansion
❌ Throws an unhandled error: Index -4194008 out of bounds for length 315run /execute positioned 40000000 0 0 run place structure minecraft:monument
❌ Tries to place and returns "Failed to place structure"
Expected behavior:
All of the three commands should fail and return "That location is not loaded". No command should throw unhandled error.
