Solved Server Crash on Startup

This has happened twice: First occurrence was solved by disabling FTB Utilities, restarting then reenabling the mod. this fix does not work again.
FTB Pyramid Reborn 1.12.2

I increased the maximum heap size from 2g to 8g, but It has not fixed the issue after the first occurrence.

Startup Script:
screen -dmS MC_Pyramid bash /home/bdkuhman/Servers/Minecraft/Pyramid/ServerStart.sh

Modified fields in settings.sh:

MIN_RAM="2048M"
MAX_RAM="8192M"
PERMGEN_SIZE="512M"

Hey

Just got this on my server today, and i found a fix

go into your saves directory and rename the craftingTiers.json file, which is possibly over 100 MB, which causes the server to not start up

It might remove your achievements, but that's better than things not starting right?

 

This should be fixed in v2.1.1 which is going onto the launcher today.

 

Hey
Please help me my server don't work https://pastebin.com/5sGuJhJ7
