Server hard crashed when Mekanism fluid pipes (mechanical pipes) and gregtech fluid pipes (used Large Naquadah fluid pipe) were placed together. Because mekanism auto joins their pipes to whatever is next to them, I had to configurate them to detach from each other. On one of the cycles of configurating the connection of the mekanism pipe, the server crashed and cannot be relaunched as it now crashes on startup every time too.

Server is a long running one with much progress and work done in it.

Crash log: crash-2024-02-08_10.41.04-server.txt

Updated to 0.2.42 and tested with this version, issue still persists as well.

I did a workaround by adding a try-catch for a NullPointerException in MechanicalPipe.java in the Mekanism mod (I cloned the Mekanism Github repo, added my patch code, and rebuilt the jar) to restore the server.
