I want blacklist for littletiles to balance modpack.
With little hammer, we can get any harvest level blocks. Harvesting higher tier ores causes players skip the progress.

Added an option to configure the highest harvest level which can be obtained via LT. I hope this solves your issue. It will be part of the upcoming pre-release. Can't tell when its ready, because it just keeps taking longer and longer. If you want a temporary solution you can disable being able to harvest vanilla blocks completely (for survival).

Thanks for your support.
My modpack project takes long time since it's huge (takes 1 year?), so I'll wait for this was implemented.

Been added to the newest pre-release which is out now!

Cool! Thanks for your working!
