Recipe for a critical mod item, the "building tool" is crafted the exact same way as a stone building wand, and the crafting table defaults to the wand. Additionally, the random named boss encounters that occur (ones with called name, the (adjuective)) can appear in said colonies, even though they are in claimed chunks, so if you are within render distance of one, there is a chance they will spawn and instawipe all colonists before you can physcially get back.
