I have the following problem: I made a custom monster lair with a custom tile design thats supposed to work similar to ogre lair(spawn a resource on destruction). However both the monster lair and the resource it spawns are invisible and unselectable most of the time(the monsters show up). The lair/resource is not selectable but gets a red "!" over it when it becomes part of my territory. I can't build on it (since i can't select it) but the tile design works on an improvement.
What am i missing?
