The first lines are from when i filled lightwells with crystals a couple minutes before so it should have everything needed

Modpack: SevTech 3.0.6
Java: 1.8.0.171
Forge 14.23.2.2651
Optifine: No

Fixed with AS 1.8.8 - wait until the pack has updated, darko is already working on the update 3.0.7

woah, that was quick. Thanks!
