I'm trying to create a new animal pen, but when I visit Robin to build it, I get an error: [Solid Foundations] Failed to setup cached custom building N.N at [53, 14] within the map Farm, see log for details. \ [Solid Foundations] Error trying to instantiate indoors for N.N: System.MissingMethodException: Constructor on type 'StardewValley.AnimalHouse' not found. What does this mean? Because of what the constructor can not be found?
Apologies for the month delay for a response. The Stardew community has largely moved on to the official Stardew forums. I suggest asking there. https://forums.stardewvalley.net/#support.16
