I didn't see a post about this one. I had all of my astral items in a Gold Chest (Iron Chests) and I used a cardboard box from mekanism on the chest to move it ad all of the astral crystals and constellation papers spilled out onto the ground. I took off the cardboard box and all of the items were still in the chest. I tried again and every time I used the cardboard box all of the crystals and papers duplicated. I discovered it on v0.4.13 and verified it was still there on the newest version 0.4.14

Thanks anyway :)
