[Bug] Crash with YTech

[Demosthenes178]

Error Behaviour

Placing YTechs aqueducts against each other with Caupona installed crashes the game to desktop. I'm not sure if this is an issue on Caupona's end or YTechs.

Expected Behaviour

Placing YTechs aqueducts against each other with Caupona installed should not crash the game to desktop

Reproduce

1. Install YTech 1.20.1-0.4.0 and Caupona 1.20.1-0.4.9
2. Place YTech's aqueducts against each other (by right clicking on the side of an aqueduct with another aqueduct).
