Maybe it is a 'local issue' but I checked it on different maps. When you place the Horse Village Guardhouse in a Village Estate, the map does not load and the game crashes. Took some time to figure it out, there are a lot of suspects on a self-made map.

Mabye you ask yourself, why would I place this building? Well, it spawns troops that you can command when the village is captured. It's a sort of living weapon supply that gives a lot of tactical options... Haven't seen it yet in the Firefly maps, but I do not play them often.
