If you explode your RBMK, leave from world \ game and try to re-join in world you get insta-crash.
My steps to reproduce:

1. Create world (im do it in creative).
2. Build and explode RBMK.
3. Leave world to main menu.
4. Re-join.

Yes, i made few test in newest versions and this bug self-fixed idk how.

Found a way to replicate it. It should be fixed now, bc in dev it has not occured since my fix. So it will be in the next update
