Gliched build act 2 - can't delete battleship production

In the other thread it was pointed that a Batleship production was frozen, and it was clarified that the BB now require the lv 3 naval base, so it is necessary to build that level to resume naval production.

As i'm in the same situation and i was building a lv 5 IC in that area i thought about deleting the Battleship construction and start it later or even elsewhere instead keeping one production point blocked for 3 days (1 to complete the IC and 2 for the Naval Base)

However ther is not a cancel production botton associated with the Battleship Production like a normal production.

Ok, these are test games and i don't mind much about a special situation that arised... but i'm asking myself:

"what if the naval base would have been damaged by an enemy? does the situation would have been the same, whit Battleship Unable to be built and cancelled?"
