(v1.21)

The title pretty much says it all. If you make a compact machine, place it in the world, upgrade it, never visit it or place anything inside of it, then break it, the machine is un-upgraded and you've lost your nether star. I seriously thought something was changed where the nether star is lost after 1 break until I realised it works fine...if there's already things inside the CM.

The fact that the Compact Machine accepts the nether star when it was never visited looks like a bug to me. That the Compact Machine looses the upgrade when it is broken without having been visited makes sense because the Machine hasn't been generated in the CM dimension.

Currently working on a 1.10.2 version, the 1.7.10 version is not being maintained anymore, sorry.
Closing all issues not relevant for the new version.
