[1.21.1][NEOFORGE] [CRITICAL] Save-bricking Crash when pumping lava using a block from another mod

[thebloxxer11]

Issue description

When playing through this mod, I decided to try and source lava from the Nether to fuel Lava Generators. Ended up bricking my save from this crash.

Steps to reproduce

Materials:
A new save (to protect existing saves), An Oritech Pump, A generator of some kind (like a lava generator), some kind of structural block (cobblestone works fine), a Tesseract from another mod listed below, and at least 2 Fluid pipes

1. In a new save, make a nether portal and cross it.
2. Navigate to a Lava Ocean, if not already over one.
3. Use the structural blocks to bridge out over the ocean and make a platform
4. Make a hole in the platform, ensuring it is over the lava.
5. Place the pump over the hole.
6. Place the generator adjacent to the pump.
7. Place the pipes connecting the pump, generator, and Tesseract.
8. Set the pipe connected to the pump to Extract.
9. Fuel the generator.
10. It should crash, and continue crashing on loading of the save.

My notes:
Having done some mod dev myself, my interpretation of the logs is that the pipes are doing something weird and causing threading issues, especially with the Tesseracts (cross-dimensional item/fluid/energy teleportation).

I will upload the crash log text file in a comment along with the mclogs, in case it expires in 90 days.

Some advice for the format: Make an optional section for comments from the reporter.

If a (crash)log is relevant for this issue, link it here: (It's almost always relevant)

It seems to only affect the Neoforge branch. I tested the same system on Fabric and it works fine.

This seems to be an issue with forgified fabric api. Just raised an issue here:
