Ok so this is all about the F keys. So one day I was just playing on minecraft, then all the suddon I had this inventory glitch. So I couldn't craft or put on armor. Then a while later, I figured out the problem. The F keys! Yep! If you press one, then the glitch can happen. (not all the time) So, here's MY story about the F keys. I was playing one of The Hunger Games servers, then it said a chest appeared at a certain spot with cords. So I fallowed them, and I was so happy... because i found a diamond hemlet! :D I went to go put it on and... it happened. :'( So far the only way I found out how to get rid of this, is close off you minecraft and open it back up. Get this real populor so maybe one of the Minecraft staff can see this and maybe fix this! :) Comment below and tell me YOUR story about the F keys. :D I love hearing from you guys!!!
