Issue: If you build gates next to each other on the same segment of wall, and one of them gets destroyed, it starts a chain reaction where they all get destroyed.
Steps to reproduce the issue:
Step 1: Build a wall.
Step 2: Build multiple gates in a row on the wall.
Step 3: Select 1 gate.
Step 4: Delete the gate, and all of them will fall.
