The game is very close to "not worth playing anymore".

My wife and I are playing this game in Realms currently. We started to play this world with my as a server. I am using a tablet, she is using a W10 computer. Most of the issues occur in both Server mode and Realms mode.

Issues:

1) We played in several different swamps trying to get slime. After several hours separately in two different swamps (4 hours approx.) only 4 slime appeared. It's impossible to accumulate enough slime balls to make the items we want.

2) We worked in an area cutting and clearing trees. After several hours over several days, grass has still not replenished. It's impossible to make "path" blocks. The grass problem happens in other areas of the game, also.

3) We have an iron farm. After several weeks it has not produced very much iron even though we have been close by building. We used a design that has proved to be spectacular in Java Realms and previous versions of MCPE.

4) Animals keep disappearing even though they are fed and fenced in. Especially certain color sheep such as cyan.

5) The game often loads with pieces of the world missing requiring logging out and back in.

6) Sometime when logging in, animals are being released from holding areas in farms because the blocks holding them in are not rendered properly.

5) When playing in the Nether for several hours, only 4 ghasts appeared. Only about 2 dozen pigmen appeared. It's impossible to get gold and experience points this way. We tried NORMAL and HARD settings. No change.

6) I downloaded the game from Realms and then uploaded it back hoping to get the game to work better. We built some things last night after replacing the game. Today I logged in and everything was fine. I came across a glitch with a spider so I logged out and back in. The version of the game from last night loaded with the exception of my personal inventory. All of my inventory is gone. I am holding nothing in my backpack. I had a chest that I put everything in before doing the download. It is in my download version but is missing from the online version. So some things are back to last night's state, the things we built last night are gone, and some things are just missing. My offline backup copy is ok. I can replace the game again in Realms, however the time we spent last night is wasted.

You need to fix the game instead of focusing on adding new features. You need to respond quicker to repairing the issues reported.
