Noticed same issue. Kelp is now no longer a useful product in MC

I can confirm this. My kelp farm no longer produces anything.

I ran a test by planting some kelp in water and watching and after half hour, none have grown. 

Basically destroys kelp as a useful item in this game now.

Had this just happen to me on my Xbox X. I'd destroy chests and the items in them wouldn't appear. Had to do a hard reset and reload the game in order to get the items to appear properly.

I can confirm I have this issue with the latest beta version on my Xbox One X

I certainly think this is something to do with the concentration of items. I still work on my world in XBox One edition of MC (due to bugs in BT) and occasionally run into difficulties converting it across (MC crashes at 0%).

Yesterday I made a copy of my save, then deleted a load of items from my warehouse AND all my maps (due to someone else commenting maps might be the cause). After this my world converted, albeit it took over an hour to do so on my XBox One X.

I intend now to open up my original save, make another copy and MOVE the items I deleted originally to a location far away from my warehouse. This will probably take me a few days, but I will report back if moving the items (rather than deleting) successfully enables me to convert my world.

EDIT : Successfully converted my world by simply moving about 20 Shulkers of materials from my warehouse. Therefore with my conversion problem its concentration of items that triggers the conversion failures.

My world now converts with the recent update, without any of the hassle of going into the nether and saving my game there. So their bug fixing has benefited me I'm pleased to say. Hopefully it enables others to successfully convert their games too!

I have the same problem - there should be an option to control the spawn rate (low, medium, high).

I can confirm this. I thought it was the way MCPE worked though?

Managed to convert my world that had previously been crashing by saving it in the nether in XBox One MC and then converting it.

I can confirm this is an issue for me as well. My world side is 186.3MB.

Like Brandon Moreton, I had an older version of the save that converted OK (older save was made 1 month ago). Only difference between the two is that the older one shows as 154.1MB while the newer one is 186.3MB

Update : Found another save, from a week after my one that successfully transferred. Identical file size (154.1MB) but this failed to transfer into the Beta. The only difference between this version and the one that succeeded was the number of chests, shulkers etc.as I'd spent the week inbetween these saves building a new warehouse and gathering items for a new build etc.

With this in mind, I took my latest version of my world, made a copy and then deleted loads of items (about 40+ chests worth) and tried transferring this into the Beta. It too failed.

So I don't think file size determines whether a world doesn't transfer - it must be something else.
