Realm weirdly auto resets in a weird way but some things remain

Lately my realm has been acting really weird, I made a brick chimney then as i got on the next day it was only halfly build, so I assumed it was a friend of mines pulling a prank since Bedrock cannot check logs, but then as i made myself diamond armor and walking around outside, the server just weirdly went down then soon went back up, I got on where all my inventory was 80% gone like when i left my build home and had my diamond armor on still. But I was back home when i shouldn't be anywhere near my home. I checked my chimney again to see just a block missing and my cows went from 4 in a pin to 2 in a pin and I marked down how many cows was there before with a sign to make sure I wasn't going crazy. A lot of things are vanishing, staying and weirdly resetting without reason and I made sure none of my friends wasn't on during this happening.
