Safe Bug (I keep lagging)

I stored all my 31 flasks and 11 healing potions, once they were put in a safe I lagged. Once I came back they were all gone!!! ALL OF MY STUFF GONE!!! Please fix this bug because I’m upset. I’d like it if I don’t lose my stuff.

I got them back, but Im still mad that I cant stop lagging!!!

the lag should be probably your connection or your phones ram
