I was playing around in my singleplayer world and I picked a silverwood slab (Thaumic Bees) with my Gravity gun and it popped off into my inventory. This caused me to crash. I am pretty positive that this is the problem because there is something in the crash report about a slab. I can't just remove the mod Thaumic Bees because I have a lot of items from that mod including very hard to get bees so if anyone knows of another way I can remove the slab from my inventory that would be great. I know there are inventory editors out there but I have never used them before so if there is a post somewhere giving a full tutorial on how to install and use an inventory editor that would be very helpful. Thanks in advance.
