Port attack

[albricias]

Attending a suggestion, I repost in this section part of a message sent before to the WIF School forum:

Japan has placed five aircraft carriers in section 3 of the naval area of the Bay of Bengal. Start a new impulse, the weather is fine and the carriers are organized, so I hope Japan can attack a british fleet anchored in the port of Trincomalee (Ceylon), adjacent to the Bay of Bengal.

But there is no option to attack: MWIF not open the attack phase port for the Japanese player, who has chosen a combined action.

I play without carrier plane units option.

Why can't japanese CV planes attack Trincomalee? According to 14.4 RAC, "A carrier plane can fly, and return from, a port attack mission that is out of range, if the port is adjacent to any hexdot in the sea area"
