We was playing and we had powah generators with tech reborn and powah cables. When I placed down an Applied Energistics Energy Acceptor the server crashed and since the if we connect and load the chunks the server crashes immediately.
Here is the latest log: https://pastebin.com/iee04aqp

This is a mod issue and nothing we are able to fix sadly.

known TR issue, unfortunately. you will need to edit the world nbt to remove the negative value being pushed TechReborn/TechReborn#3085

This bug got a possible fix in powah.
