"My friend and I are playing Regrowth 0.8 and we finally made it to making thaumcraft golems. First thing we did was set a golem down in an essence farm and notice that the golem was breaking both the crops and the crop sticks. The golem has been equipped with a Gather core and when we noticed the problem we also added an Ordo upgrade to see if that resolved the issue, to no avail. We even tried a Thaumium golem with the same result.
After further testing the golem works as it should with cotton and Barely. ( Only 2 we tested on. ) The problem appears to be with the magical crops.
Just wanted to give you a heads up."
I have made a post with the same info provided above in the
agricraft thread as well. I decided it would do well here as this is the only pack I have found that is causing the problem from all the searching I have done on the issue.
