Main Servers And Bugs [PE]

I like to play on the main servers (the servers that are usually found in the servers section without having yo join (ex: CubeCraft, Hive) but these servers always seem to have bugs for me. In one of them, i couldn't even grab certain items or craft anything
in their games..Sometimes items don't load and instead of it being a lucky block its just Steve. Maybe it has to do with space on my phone or maybe playing on mobile cuts back the quality.
