Minor Getting stuck in the cryo unit

[Flaborized]

If you hold the up movement key when you latejoin in on a map that starts you out in cryo you walk into the cryo and can get stuck. The top three tiles and specifically the top middle tile should be solid and you shouldn't be able to walk into them.

many maps include window tiles on the upper row of the freezer for that reason, i'll see about adding them to those that don't have it yet.
