Hi
If I break a Compact Machine block with my Tinker pickax, my client crashes.
Below is a copy of the crash log, let me know if there is something more you need to know or like me to test.

I hop this is something you can fix :-)

Crash log:

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.

I cannot reproduce this. Any ideas on what needs to happen so this error occurs?

Sorry, I can´t remember in top of my head which pickaxe I did use, need to take a closer look next yr when I get home. (This Sunday)

Hmm, reopen this issue when you know how I can reproduce this.

I just encountered this same issue today.

Seems, so far it is any tinker's pickaxe I have tried on regular CMs, the upgraded ones have no issue but a visual duplication which I've yet to check if that was fixed.

I'm currently using the 1.17 release of CM with forge 1291.
