I probably should add that I was not able to reproduce it using Create 6.0.6

This crash report is related to trying to shift click copycat fence with wrench:

We'r also having this issue, i modified the code to work with Create 6.0.8 api changes and it seems to be running so far. I did not test everything but copycat blocks are working again without any issues. I created a PR #180

Thanks for the PR. This fix has been released as v1.1.9
