Expected Behavior

the problem is in the multi-block structure itself.
the excavator does not see the bucket and cannot dig because of this, although the bucket is actually present.

Actual Behavior

Steps to reproduce

build excavator

Debug Crash Log

.

Since you didn't provide a debug crash, we don't have a modlist from you.
If you are using Optifine or Rubidium, that may very well be why the bucket wheel is invisible.

Additionally, did you take a core sample where the excavator is placed? What minerals are you expecting there?
