Prior to this, Sirius B was a working planet. Alone, too, works.
But now, it is enough to teleport to this planet - and you will get the crash of the server.

version game [1.7.10]
server [KCauldron]

Change the option "load chunk on request" to false in cauldron.yml

IT WORKS!
This is true happiness.
Thaaaaank!
