I uesd the schematic_and_quill frame to select the space that includes the mechanical_arm.At first the mechanical_arm was in the north side.



Then I print it.If it faces the same direction as before，it is normal...


But when I rotate it, it will have problems.It lose its input...


Sometimes it even lose all the targets...

The same situation occurs in the mirror...


So these are the questions I want to talk about.

Thanks for reporting, we have already fixed this issue so it should work properly once the next patch is released.
