FTB INFINITY 1.9.0: Catalyst Craft
FTB Infinity 1.9.0
Only rules being common sense.
No intentionally causing severe lag.
Accept that if you grief people, they will most likely grief back.
Routine world backups.
I am reminding you here in capital letters:
THE SERVER IS RUNNING VERSION 1.9.0 SO REMEMBER TO SELECT 1.9.0 FROM THE DROP DOWN MENU.
If you get a mod mismatch error, I would suggest checking this is the version you have, you can see the version in the bottom left of the title screen.
