Description
Schematicannon only requests outer block (e.g., Placard) but places it with embedded container contents (e.g., Shulker full of items)
When a schematic is captured in a Creative world containing a Placard that has a Shulker Box (or other item-containing container) stored inside it, then the schematic is used in another world/server, the Schematicannon only requests the Placard block as a required material. However, after printing, the placed Placard still contains the stored Shulker Box with its full contents. This allows transferring items into a target world without the cannon requesting those items as inputs.
This appears to be caused by the Schematicannon validating only the outer block requirement and not accounting for embedded NBT/BlockEntity data that contains items.
Steps to reproduce
- Create a Creative world (World A).
- Place a Placard (or another block/entity capable of storing an item internally).
- Put a Shulker Box full of items inside the Placard (or store an item that itself contains items, e.g., backpack/container item).
- Create a schematic of that build using Create schematics.
- Move the schematic to another world/server (World B).
- Print the schematic using a Schematicannon in World B.
- Observe requested materials in the Schematicannon.
Expected behavior
- Require all contained items (including container contents / NBT) as materials, or
- Sanitize/strip stored items/NBT so the printed block does not include embedded contents, or
- Refuse to print block entities with inventory-like contents unless explicitly provided.
Actual behavior
- The Schematicannon only asks for the outer block (e.g., Placard).
- The placed block includes the embedded stored item (e.g., Shulker Box) and its contents anyway.
- This allows importing items into a server/world without providing those items to the cannon.
Impact / abuse potential
- Enables item injection into survival servers from a creative-prepped schematic.
- Server-side bans on Placards reduce the specific case, but players can re-enable/unban and repeat.
- May not be limited to Placards (suspected other carriers: item frames, shulkers containing other containers, backpacks, etc.).
Notes / additional testing ideas
- Test other block entities and item carriers (item frames, armor stands, lecterns, signs/placards, modded storage blocks).
- Test nested containers (Shulker → Backpack → Items).
- Check whether schematic data includes full BlockEntity NBT and whether the print validation ignores it.

Description
Schematicannon only requests outer block (e.g., Placard) but places it with embedded container contents (e.g., Shulker full of items)
When a schematic is captured in a Creative world containing a Placard that has a Shulker Box (or other item-containing container) stored inside it, then the schematic is used in another world/server, the Schematicannon only requests the Placard block as a required material. However, after printing, the placed Placard still contains the stored Shulker Box with its full contents. This allows transferring items into a target world without the cannon requesting those items as inputs.
This appears to be caused by the Schematicannon validating only the outer block requirement and not accounting for embedded NBT/BlockEntity data that contains items.
