Entity?

The NPCs in versions 1.10 onwards, ceased to be recognized by the commands as entities, both by the TYPE tag and the NAME tag.
It is something that causes conflict with some maps created based mainly on NPCs

Summon?

The NPCs stopped being able to be achieved with commands from version 1.8, it is a bit annoying to resort to external programs to obtain them.

Dialog?

The dialogues of the NPCs can not be modified in Android in versions 1.10 onwards.

Please, these bugs cause problems to the mapmakers of the platform, it would be appreciated if they would fix them in the future official 1.11 or future delivery
