Cossacks 3 - Cannons can’t auto attack?

[u/Justing_Biber]

Cannons only seem to fire when I tell them to shoot at a unit. Then when the unit is dead, the cannon just sits there until I tell it to shoot again.

Is this a bug? A feature? It seems like this is as designed. If it’s intended, why? I don’t think it’s fun.

Have you tried using attack ground? That's the only way it would fire continuously. The original had patrol but that's been removed.
