I'm getting a consistent CTD with 1.1.0.23. The log is here (https://paste.ee/p/Y9ydR), and to replicate it create a creative world then fly straight in a random direction. The crash can take a few minutes to happen but it always happens. The ore configuration is here (https://paste.ee/p/YPNSJ; Yes the numbers are insane atm, will balance later).

Versions:

• MC 1.12.1
• Forge 2467
• BedrockOres MC1.12-1.1.0.23

Gneh, looks like Minecraft causes neighbors to get loaded when setting a block... fixed in 7df7963.
New version coming shortly.

Thank you :)
