This release fixes an issue in **new world creation** where water creatures were not spawning naturally because the FLAT type of world height of the world became -63, i.e., one block above -64. Unfortunately, this fix doesn't change existing worlds. It can only affect new worlds.
### To fix current worlds
**Use are your own risk! Take a backup copy of your world beforehand**
You need to edit or replace the **level.dat** file in the `bskyblock_world` folder. The simple approach is to copy a `level.dat` file from a generic world and paste over it, e.g. the `world` folder's copy. Then restart the server, and it should work. Alternatively, if you have a NBT editor, then you can change the **level.dat** file of the world NBT tags to look like this:

## Compatibility
✔️ BentoBox API 2.7.1 or later **only**
✔️ Minecraft 1.21.3+ **only**
✔️ Java 21
## Upgrading
0. Make sure you are upgrading to MC 1.21.3 or later!
1. Stop the server. Make a backup just in case.
2. Copy this jar over the old one
3. Restart the server
4. You should be good to go!
