Invasion can't be stopped?

[colprice]

I've just defeated a UK invasion fleet for my Japanese possession of Borneo. 
The AAR page shows that the UK failed its target (7/8 invasion TRs sunk), so no target bonus for UK.
The next turn, I'm informed that troops were landing anyway..
Is this intended (it seems to be a hangover from TRW2)?

What was the battle outcome?

It needs to be any victory in order for the Attacker (invader) to succeed, otherwise the defender should quash that particular force.

The actual status of the TRs is of relatively small importance.

Plus, there's always a chance of the defending forces being sufficiently damaged that they enemy can try again in the next turn and get a 'free' invasion against reduced defences.
