Partner Rank: 2

Partner Team Reporting: Gamemode One

Verification builds and Platforms: R21U5H1 & 1.21.60.28_RC0

Summary:

If a jigsaw structure contains a custom block with the component `minecraft:tick` the game crashes if the jigsaw loads naturally as part of world gen or forced via /place

Impact:

Creators experimenting with the Jigsaw feature can not use some of their custom blocks in jigsaw structures

Repro Steps:

1. Download the demo.mcaddon
2. Import demo.mcaddon
3. Create a world with the Jigsaw experiment enabled and apply the demo addon
4. Run `/place jigsaw mike:ew7x4 mike:ew7x4 2 ~ ~ ~ false` to confirm a jigsaw with a non ticking version of die is placeable
5. Fly away and run `/place jigsaw mike:ew7x4_tick mike:ew7x4_tick 2 ~ ~ ~ false`
6. Observe the game crashes
7. Relaunch MC and join the world
8. Run `/structure load mike:ewhall_tick ~ ~ ~` and confirm the structure does not crash the game

Observed Results:

If a structure placed by jigsaws contains a block with minecraft:tick the game crashes.

Expected Results:

The game does not crash when loading a jigsaw structure with custom blocks with any component.

Screenshots/Videos attached: No
