Pingot Pet is dangerous..

So yesterday, I was using a Pingot Pet in Oasis FTB.
The Pingot Pet extracts ores from the ground into your inventory.
I obtained 11 coal ore and 6 ores named "OreBlock.Unknown" from the Mekanism mod. These ores have a missing texture.
My theory is that I Extracted an ore that crashes me. Every time I attempt to open my inventory, I am met with a crash. The crash happens so fast that I cannot even get a glimpse of my inventory.
I cannot do anything that makes my inventory visible, for example crafting, smelting, looking through my
chests etc.

Could any staff help me in what to do to save my inventory.

Thank you ~ patuator
