Chest NOT OPENING In Mulitplayer

(actually the bug is for iPad Air)
In some servers, even when i tap on the chest multiple times, i still cannot get it to open. Only after i walked a few blocks then the chest will open. This is irritating as in Survival Games, when you want to loot, the chest will not open and after you walk for a while, then it will open, then other players will kill you. This bug has been present on all servers i come across (13 servers) but is worst in LifeBoat Survival Games (sg.lbsg.net:19132). Please fix!!!
