Invincibility Machine Patch

Hey there,

It has come to my attention that some players build a Slimy - Saddle invincibility machine and then exploit some bosses. If this could be patched or removed, this would help alot and make the DTP more fair.

Aren’t main and mirror mob regioned? Or am I just incredibly forgetful?
If not, I believe making the spawning of bosses impossible on both would solve the problem, as /boss doesn’t allow you to build. Although I’m not sure how Rofle will treat this.
