If you use ore excavation to "vein mine" a group of gravel or sand ores (e.g. 9 blocks of iron gravel ore), you get a crash.

This is reproducible 100% of the times I have tried it. I reported it to the ore excavation mod author, but he thinks it's a problem with ex nihilo omia. Funwayguy/OreExcavation#8

I have attached MultiMC logs, crash report, and latest.log at http://games.technoplaza.net/temp/eno-hammercrash.zip.

MC Version 1.10.2

Please let me know if you need more information or any help testing. More than happy to do so. Thanks for a great mod.
