Summary
When updating a BDS instance to the latest version by only copying certain files across (namely the executable), BDS appears to start and run normally but when playing there are significant issues.
So far reports have been received for:
World generation broken - all new chunks are stone only in all dimensions
Mob spawning broken - no new mobs spawn
Crafting broken - some wooden items cannot be crafted
How to reproduce
Extract the 1.14.60 BDS files
Run BDS and connect to the server, generate some of the world
Stop the BDS server and copy the 1.16.0 executable over the 1.14.60 instance
Run BDS again and note it starts without issue
Connect with a client and explore new areas, note the world generates as stone and no new mobs are spawned
What I expected to happen...
It's possible an error in the console would assist admins in identifying the issue.
What actually happened...
The server appeared to start normally.
Mod Note
If this issue is occurring for you please do the following:
Extract the latest BDS files.
Copy the worlds folder, server.properties, whitelist.json and permissions.json from the old folder into the new one. Don't copy across anything else.
Run BDS
If your BDS server is hosted by a service provider, please contact their support and reference this bug report, they may need to assist in upgrading your servers files.
If you are using a Docker image, please contact the owner of the image to update as required.

Will replacing the worlds folder with the new update delete the previous world? Is it possible to copy over part of the old world over as well?
