Summary

This is a testing report that I (infrequently) use to test issues with MojiraBot (from the Mojira Discord).
I apologize for any notifications you receive for this ticket being updated, or any times this ticket interrupts your work on the bug tracker.

Original Description (of the invalid report):

Using structure blocks, structures can be transferred from world to world by copying the nbt file created between the world folders. However, item frames with maps do not usually copy correctly into a world. I'm attaching a screenshot with this bug. You can see the normal item frame on the left as well as the enlarged item frame on the right. When the large item frame is pick-blocked, a map of that area is given to the player, which updates the map on the item frame.

How to reproduce:

1. Create a new world
2. Create a map, load it, and put it into an item frame
3. Create a structure file containing the item frame, with Include entities set to ON
4. Create a second new world
5. Copy the "generated" folder from the first world to the second world
6. Use a structure block to load in the item frame
7. Notice that it is an empty item frame but it is enlarged as if it contains a map.
