another phenomenon that can happen is that one can get their tube doors out-of-sync, especially if you are a keyboard-person who uses the Q and W keys. if you forget to check the status of a tube before you open it, you may open an empty tube which then prevents you from reloading it until you close it. discovery is the key element because there is no status light or indication that a tube is open, at any time.

a related issue is that SH3 and SH4-Uboat theatre will allow a user to fire a torpedo with the doors closed but the Pacific Theatre will not allow that. so, if you are used to playing the Atlantic side of things, playing the Pacific will throw you curves not previously encountered.
