Since it wont let me select Bedrock Edition in the version choose, I'll hope this doesnt confuse people using MCPE tag for now.
So when trying to craft an item, the crafted item will sometimes dissapear immediately after it was crafted. You'll see the item in the inventory for a split second, and then it's gone. When creating Cakes (this is when the glitch first happened) the missing cake would end up taking two of the buckets with it too. I tried crafting other items and it's all hit or miss on if they dissapear or not.
The problem was first discovered today at 10:00am November 8, 2019 and so far still persists in the realm. As far as I can tell this is only a realm related issue. I didnt have this problem last night or earlier when I was playing. So far only today this has happened.
This maybe have something to do with the mining lag that's been going on lately?
