Describe the bug

If a block dispenser is powered before or during being moved by a piston, and not un-powered, the dispenser will place/dispense its currently selected item and be pushed by the piston; all remaining items inside the dispenser will be deleted. This does not occur if the dispenser is un-powered before being pushed.

To Reproduce
Steps to reproduce the behavior:
Option A:

1. ) Place items in block dispenser
2. ) Power block dispenser
3. ) Move block dispenser with piston

Option B:

1. ) Place items in block dispenser
2. ) Power block dispenser and piston at the same time

Expected behavior

Block dispenser will place/dispense its currently selected item from its inventory, then be pushed by the piston and retain its remaining inventory.

Screenshots

Both situations result in deleted inventories.

Info (please complete the following information):

• Modpack Version: 2.77.5
• Server or Singleplayer: Singleplayer
• Version the world was created on: 2.77.5

Additional context

I would prefer this issue to remain unfixed rather than have block dispensers removed or be unable to be pushed by pistons.

Closed due to inactivity and wontfix.

Edge case. Quark’s TE moving ability is obviously conflicting with how BWM does inventory for BDs. As Quark no longer updates old versions this may have to be part of QuarkFork. Easy solution would be making BDs unpushable but all the redstone nerds will be up in arms :)
