Describe the bug
DnxChunks region files are used across worlds somehow

To Reproduce
Steps to reproduce the behavior:

1. go to a new map in singleplayer
2. activate the client debug renderer to see terrain blocks
3. spawn props
4. write down the coordinates
5. go to a new singeplayer world
6. teleport to the coordinates
7. spawn props
8. search for blue terrain in the air where no blocks are located

DynamX version
latest beta branch

Expected behavior
The props should adapt to the terrain of the new world and not to that of the old one

Fixed in commit efc71fe
