Issue type:

• 🐛 Bug

Short description:

Minecraft can crash when deleting an InDy network via e.g. replacing it with air via /fill.

Steps to reproduce the problem:

Unable to reproduce reliably. Involved /filling the network in the world attached below, although other (not connected) networks were present at the time of the original crashes that were deleted and so I haven't been able to add back to the world.

Feel free to wontfix or close given the lack of information and irreproducibility - I'm mostly reporting in the off-chance you spot something in the crash reports that makes sense and can be fixed.

World:
FillCrash.zip

Expected behaviour:

Weird network behaviour at worst, nothing at best. At the very least, not a crash.

Versions:

• Minecraft: 1.20.1
• Forge: 47.1.0

Log file:

https://pastebin.com/XgL1LW3r - initial crash
https://pastebin.com/EUwsxDMV - second crash (probably the same reason as the first)
Unable to reproduce since then.

Thanks for reporting!
