Boat disappears on re-entering world

This has now happened multiple times

1. I'm on water, in a boat
2. I switch to another app on the iPad for a while
3. I return to Minecraft and re-select my world to enter
4. When I enter the world I am on the water with no boat and sync.

This has now happened a few times, can confirm it is a bug.

I entered it before but you deleted the issue.

I know you get a lot of crap JIRA issues, but I'm pretty sure this is a thing.
