MineTweaker3-1.7.10-3.0.9C
AgriCraft-1.7.10-1.4.0-alpha-4-1.7.10

I cannot reload a single player game. I do not know if this is an issue with minetweaker or with agricraft.
I don't have a script changing growing baseblocks.

This also prevents me from creating new single player worlds.

Can you also give me your Minetweaker script please, I'll try to duplicate and fix this.

I added a null check so this shouldnt happen anymore
