I eventually crashed my game after a back to back use of the nether star hammer. It was the best thing but this happened. Rip.

I can't reproduce this, can you tell me exactly what you were doing to make this happen please?

Sorry. I was drilling under the map nonstop since it was so satisfying to see that hammer drill through so much stuff. In the near end of it though, the breaking effect of the hammer started stuttering. Maybe it's because of a ram issue since the computer I used wasn't the best for modded minecraft.

Is there no issue when the nether star hammer is used in different directions as quickly as possible. The enchantments I had on the hammer were mending and unbreaking 3. I also had a mod n called Better Mending which lets me heal the hammer by shift clicking to drain my xp.

I still don't understand how you've caused this issue, however I've rewritten some parts for the Nether Star Hammer so it should work better now. These changes are in the latest version, v1.6.4 for both MC 1.10.2 and 1.11.2. Please let me know if it works or not. If not, please describe exactly what you do. Perhaps even a video or GIF showing what happens would be ideal?

Closing this due to no response in a very long time.
