In carousal it started with no one getting their units for the first neutral wave. Then we could buy and put stuff on, but an invisible, non-active unit took up a spot. The next round the new unit (#2) you put on the board disappeared. No combat at any point happened. By 2nd carousal the unit you got would stay tethered to you AFTER the 2-5 round and you could not sell or place them. They followed your sprite around on the combat board. After round 2-5 the game stopped working entirely and timers stopped existing.
