This is not related to Chalk. You have a corrupted Aludel base block somewhere in your world

Proof:
In your logs;
com.pahimar.ee3.tileentity.TileEntityAludel.func_70296_d(TileEntityAludel.java:313)

That's the markDirty method in TileEntityAludel;
https://github.com/pahimar/Equivalent-Exchange-3/blob/master/src/main/java/com/pahimar/ee3/tileentity/TileEntityAludel.java#L313-313

Try this again with a new world

Unable to reproduce, weird, wonder how that happened
