So I was in my survival world, doing the usual task of collecting XP at my enderman farm, when I was cleaning out my inventory. When I threw an unwanted ender stone block, I didn't see it being thrown away into the void. And I went to open my inventory to find that the block I had thrown had gone straight to the boots armour slot in my inventory, overwriting my diamond boots. I went to my ender chest to get some diamonds, and proceeded to craft a new pair of boots. After crafting them, I accidentally dropped them, and when I went to pick them up, they went to my leggings armour slot, overwriting what I was wearing there, too. I decided to individually test my mods, to try and narrow the problem down. eventually I realised that Forge was the culprit. I checked the FML logs, and there are no stack traces or anything serious there.
