I was playing hide and I saw a hider and seeker get out of the map by using block reveals and ghost blocks.
Hive you should make your mode to adventure mode in hide and just letting you hit seekers and hiders and not placing blocks.Thank-you. By the way this glitch is mainly used on Farm map and the newer maps.
Sadly, it is impossible with the current system to change the mode from Survival to Adventure mode, since you are required to hit blocks (damaging them) to find hiders.
