Any ideas?

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.

there we go, try again

Can you reproduce this with a new world? If not, try deleting the compactmachines folder in the world's save folder.

Seems like the issue was caused by Compact Machines default dimension selection. I would recommend that it instead select the first available dimension instead of defaulting to 3. Setting the dimension to 25 let me back in.
