Description of the problem: When i was just walking around the betweenlands, chat started spamming "CCL has caught an exeption whilst rendering a block" And then my game starts having big lag spikes every 2 seconds. The game also starts unloading the world.

How to reproduce:

1. Go into the betweenlands
2. Walk around for a bit
3. The error should pop up in chat (helps to have higher render distance)

Expected result:

Nothing

Actual result:

My game was basically snapped to dust.

The error seemed to be with a block called "pitstone"
