Way more screwed up than that. Decided I wanted to do a hippo lake with a massive underwater viewing plaza (think one acre or more), glass walls, glass ceiling to see them swimming overhead, all that good stuff. This viewing area would be so large I decided to put a food court and shopping area in part of it to draw people in- all underwater, mind you. So I went ahead and did this, with the game paused. Built the whole area stalls and all, more glass walls and ceiling than you ever saw, put the water in, lifted the whole group out of the water to start on the tunnel to connect with the rest of the world, unpaused for something else... then remembered those poor vendors who had dropped in with the new stalls. The second after hiring I literally chucked them into a giant lake.
