Don't mark my bug reports as Cannot reproduce
Steps to reproduce in 1.18 pre-release 4:
1. Create a superflat world
2. Run `/tp 29999983 4.00 29999983`
3. Put your render distance to 20
4. Place a piston down next to a clock
This happens due to:
attempting to get a chunk that cannot be created due to being outside of the world border. The game then attempts to upgrade that chunk, which leads to multiple issue. The main one is that it attempts to load the chunks next to this chunk, which is also outside of the world border. It's bad but can easily be fixed by having a check either in `ChunkMap::schedule` to prevent chunks beyond: 1875010 (wb chunk + 12) or change the invalid chunk position to not load these chunks to begin with
