Block Placer makes blocks vanish
โ Checklist
- [X] I am using the official english version of Slimefun and did not modify the jar.
- [X] I am using an up to date "DEV" (not "RC") version of Slimefun.
- [X] I am aware that issues related to Slimefun addons need to be reported on their bug trackers and not here.
- [X] I searched for similar open issues and could not find an existing bug report on this.
๐ Description
When placing a block, which needs to be supported (eg: Redstone Dust, Repeater, Redstone Torch) on top of a Block Placer, when the Block Placer is broken, the block on top does not drop into item form.
I only checked with Redstone Dust, Repeaters, and Redstone Torches. I broke the block placer first using a Netherite Pickaxe, only with Vanilla Enchants
๐ Reproduction Steps
- Place a Block Placer
- Place Any of the following on top of Block Placer
- Redstone Dust
- Redstone Repeater
- Redstone Torch
- Break the Block Placer
๐ก Expected Behavior
When the Block Placer is broken, the block on top is expected to drop as an Item, which it does not.

Can confirm. This works with all Slimefun machines/blocks. Slimefun blocks will destroy and not drop the top blocks (or any sides) if the that blocks need other block to place it.
