I have a bedrock server running on a windows 10 PC,
Most of the world seems to be fine, however we have found a large area of the world with missing chunks, the gaps have no bedrock at the bottom and there are about 20 missing chunks around each other missing in the world, and some in the area are also suddenly higher by 6/10 blocks ... the map for this area just has large black squares where the chunks are not there...
We can fall off the world in any of these.... and also we can build steps down into them!

I have been googling fixing missing chunks but cannot find anything to do with bedrock, only JAVA servers (our JAVA server is on the same machine and running fine)
are there any server tools to fix bedrock chunks?

Just restarted the server to see if it made a difference, however it still is doing the same thing, when using a map in the affected area, the missing sections are black squares on the map
