Ok not sure on version. Currently 1.10 bedrock code playing on realm.

You have to be aware of what i am reporting. Please don't ask about reproducing as from what i see on youtube its widespread.

There is a big problem with all sorts of things just passing through bocks. Players, passive mobs. I have no way to tell on agressive mobs. But on realms have this issue that is not present if i play on my local console.

First noticed several updates. Horses i had tamed and named were found wondering outside cobble wall housing them. Was able to fix by adding wood fence inside wall. They did seem to pass fences too. But not doubled up. Not sure if this was realm specific.

Next tried flying machines to map areas and later wanted to move sheep and other mobs to end islands to avoid increased lag on overworld. No matter the method. Carts or boats would pass through blocks and die in void. Limited testing showed this to at least be less of a problem local than on realm. If i could upload my current world to realms would just dl do local and upload game to realm. But since file size reached 600mb it keeps failing during upload. 

I then tried to do a ice bridge machine to get around end corruption glitch. Did not mind. Figured it would be fun. Built a verified working on bedrock version. After a time the armor stand would pass through a block and just get launched. That was kind of funny the first few times. So i moddified and took the place of the stand. Only to pass my self through blocks and end up behind the machine. Or the lag and fall through ice as it forms. Real treat.

Both of these in limited testing not an issue off realm.

Now trying to get prepared for the upcoming changes to villagers and villages. So building a new breeder. They keep passing through blocks. Again limited testing local seems to be fine. 

I just have to wonder. Knowing the history of microsoft and the hotmail issues. I have to wonder maybe they can't run realms on ms servers. Maybe they should switch to linux based servers to host realms. Hell they could probably run the simulation range out to max and run better than now.

If they can't permanently address this. Could they work with gportal and other hosting sites to have the same seamless integration on xbox that realms has. If they can't make realms what it should be. Please make way for those that can.

I hope this is taken as intened. Honest feedback. I really like this game. And only came to xbox from ps4 foŕ the hosting fucntion. And really hate how realms is making hate that choice sometimes.
