Nodebreaker in Survival Mode Outputs Block to Front Instead of Back
When playing in Survival mode, the Nodebreaker from Pipeworks outputs blocks to the front of the machine instead of the back. This issue does not occur in Creative mode.
To reproduce the bug, follow these steps:
Start a VoxeLibre (formerly MineClone2) server.
Setup a Nodebreaker in your world.
Enter Survival mode.
Use the Nodebreaker to break a block. Observe that the outputted block appears in front of the Nodebreaker.
Expected Behavior:
The Nodebreaker should output the broken block to the back of the machine, regardless of the game mode.
Environment:
Minetest version 5.8.0
Additional Information:
This bug only occurs in Survival mode. In Creative mode, the Nodebreaker works as intended.
Is this a Pipeworks bug or Mineclone2 and does anyone knows how to solve it?
