Description:
Based on the log it seems you're ungracefully handling there being a negative quantity of LF in an energy cube.
This is causing my server to go into an infinite crash loop, all backups of my world from before this occurred have been deleted because of the crash loop...

Would be helpful if your comimts were more than "fixed a bug".
If I knew what bug you fixed I'd potentially be able to avoid having to make this issue.
I can't dig you to hard though, I do the same thing at work.

Steps to Reproduce:

• I'm not certain on this but I suspect inputting to AND outputting from an energy cube into a single line caused this. It wasn't an immediate crash though after I had done that.

Technical Information:

• Minecraft: 1.17.1
• Fabric API: fabric-api-0.40.8+1.17.jar
• Industrial Revolution: indrev-1.11.0-alpha.1.jar
• Modpack: All of Fabric 4 1.0.0

Logs:

• Server Crash Log for indrev-1.11.0-alpha.1.jar : crash-2021-10-16_08.43.37-server.txt
• Server Crash Log for indrev-1.11.0-alpha.3.jar : crash-2021-10-16_20.24.25-server.txt

we got same error on alpha 1
crash-2021-10-17_21.01.15-server.txt

so we updated to alpha 3 ...now energy seems to work for us but items throw error? same infinite crashloop, but not on connect, this time no one connects and it is crashing:

crash-2021-10-21_17.55.00-server.txt

full boot:
2021-10-21-7.log

only way to fix crashloop for me was deleting indrev-1.11.0-alpha.3.jar and startup, save/stop, insert indrev-1.11.0-alpha
.3.jar again and startup again

Thanks for reporting, this was fixed as of 1.11.0-alpha.4 which is available on curseforge.
