What happened?

I have a save that is pretty long. I have it backed up and it appears that it might be coming from PNC Repressuized. but how can that be because when I tried it on a new world, everything works fine. Not sure what to do.

(PNC author) Thanks for tracking that down, I was a bit perturbed by the sudden flood of issues raised against PNC...

the same crash

me too..

If you're running into this issue, try downgrading pneumaticcraft to the previous version which can be found here pneumaticcraft-repressurized-6.0.17+mc1.20.1.jar.

This didn't work for me unfortunately, still the same crash.

This should atleast rule out any crashes with pneumatic craft if not resolve any issues caused by the following pneumatic updates;

• Stopped the Pneumatic Armor Magnet upgrade working in spectator mode
• Drones no longer drop items with Vanishing Curse when they die
  • Exception: such items will still be dropped if the drone is wrenched by the owning player (and only the owning player)
• Fixed a race condition when using Computercraft to control Air Cannons

Jebraltar has traced this to GTCeu, GregTechCEu/GregTech-Modern#2644, and it will be fixed their side with PR GregTechCEu/GregTech-Modern#2650, and the pack will be updated ASAP after that
