Space vaults spawning incorrectly

Created by: D3athrow-Issues

(WEB REPORT BY: boptser REMOTE: 172.93.109.202:7777) Every second vault I've encountered in space has been cut off at one of its edges, often breaking its content as the mobs die and loot is easy to access

the vaults aren't spawned at the edge of a z level so that's not the reason they are broken
