On 2 different colonies, ive had wandering liches come, send Giant Skeletons at me. They use their hook ability to hook my colonists into melee range, except a lot of the time they are hooked, they cease to exist. They are gone from my colonists tab on the top, they are not on the map, the social tab, etc. Im assuming this is a bug and am wondering what the cause of this is or how to fix it (or get my colonists back)
