> ## Issue: you cannot build walls over/through aquaducts without leaving a gap

For Byzantines, if you have an aquaduct, and then want to build a wall that would overlap the aquaduct, it always leaves a gap and enemy units can pass through.

> ### Trigger Event: n/a

(what was happening at the time of the issue. this could be an action you or another player took right before the issue started)

> ### Repro Steps:

1. Build an aquaduct

2. Build a wall that overlaps it
