Confused

I really like this game and was mining the other day I mined all the way to the place where the scarabs and the guy that looks like Anubis is and my inventory got full so I went back up to put some stuff away,but it wouldnt let me open my chest.I thought it was the settings so I went to settings and fiddled with them.That wasnt the problem.I went back on my world and tried to open different chests but it still wouldnt work.I later found out that my shelves were empty too.I dont know if this is a glitch or what,but PLEAAASSSEEE fix it I cant play if my inventory is full.To top it off this game is amazing but I cant open my chests and my shelves are empty for some reason. PLEAAAASSSEEE fix it i really like this game!!!!
