Put the summary of the bug you're having here

What I expected to happen was...: A pillar of scaffolding

What actually happened was...: Scaffolding moves up one block when clicked with another scaffolding block, instead of just keeping all of the blocks.

Steps to Reproduce:
1. Make the first picture's structure
2. Add scaffolding on the bottom block 4 times
3. Add scaffolding in the middle of the pillar around 4 times.

4. Add Scaffolding on the top of the ghost scaffolding to make it disappear
