A Can Em All truck not spawning has three causes, and only one of them is a bug. New trucks are gated on the state of your factory: roughly half the previous load has to be dead, and the total object count has to be low. When that count drifts because of the Cold Storage upgrade, the game thinks the floor is clear and sends nothing at all.

Can Em All truck not spawning has three causes

  1. By design — the factory is not clear enough, so the game withholds the next truck.
  2. The Cold Storage bug — the freezer upgrade corrupts the object count and it drifts lower every day until no truck ever comes.
  3. The run is over — once you have bought the final key, no trucks spawn at all, and that is intended.

There is also a fourth case that looks identical: a creature wedged out of reach that the game still counts as alive.

The factory is not clear yet

This is the normal case, and it is the game working as designed rather than a fault.

  1. Check the object count. Bodies and cans on the floor, the contents of your vacuum, and cans piled in front of the tube all count.
  2. Kill about half of the previous load before you expect another truck. A set share of it has to be dead.
  3. Ship the cans down the tube. Processing the previous load quickly is what brings the trucks back faster.

One detail that catches people: killing the creatures too quickly makes the next truck take longer to appear. The wait is part of the pacing. The belt setup that keeps the floor clear in the first place is in the conveyor belt guide.

The Cold Storage bug

With the Cold Storage freezer upgrade bought, the game loses track of its total entity count and of how many creatures are in the pool. The number drifts lower every day, and eventually the game believes the floor is clear and stops sending anything. It compounds day by day, so it starts as an occasional late truck and becomes permanent.

  1. Exit to the main menu and continue the save, or restart the game.
  2. Check whether a truck arrives afterwards.
  3. If it does, the count is back in line.

The other late-run causes, including a key that stays flagged as unlocked, are in the stuck in the endgame guide.

The run is already over

Once you have bought the final exit key, the run is finished and no trucks spawn. That is intended behaviour, not a fault.

  1. If you have not taken the ending yet, use the elevator behind the upstairs exit door.
  2. If you have taken it, return to the main menu and pick Continue to keep playing your factory.

The route to the elevator is in the ending guide.

Creatures alive but out of reach

Late in the game, creatures wedge themselves into walls and into the ceiling beams. The game keeps counting them, so no truck comes even though the floor looks empty.

  1. Look at where your turrets are aiming. One pointing at a wall or up into the rafters is pointing at a creature stuck nearby.
  2. Follow the line of sight and kill it.
  3. If the angle is impossible, reload the game instead.

Turrets are the only reliable way to find these creatures. The turrets guide explains what they track and what they miss.
