WorldStabilizer no longer works as of 1.11, it no longer protects against the 1km spawn bug (and its presence in 1.11 seems to cause the bug to evolve into a vicious kraken) so take special care when spawning crafts containing at least these parts, or don't use them anymore:

• J Deployment Bay
• J Inline Large Docking Port
• Avatar Cargo Ramp
• Humpback Cargo Ramp
• Stail Cargo Bay (Mk1, not Mk2)
