Naval invasion won't execute

[7509attack]

So I looked at other threads here and believe I have everything I need for a naval invasion, but with I click the arrow to activate nothing happens. As a summary I have:
1. Assigned units to an army.
2. Clicked on the arrow for naval invasion.
3. Set the invasion start and end points.
4. Waited for invasion to be ready.
5. Had sea superiority through every area.

Everything was green, and I had a green arrow for invasion (click to activate) but the assigned units never go anywhere when I activate.

Been playing as Japan, tried multiple different units, anywhere from 2 to 10 divisions. Had plenty of available convoys as well.

What am I doing wrong?

I'm not 100% certain on all the naval mechanics yet.

First off make sure it says "army/number of divisions and number of transports" on the battle plan arrow. A lot of times it will bug out and not recognize the order by saying "no division and 0 transports." Why? I have no idea. I'll get this problem all the time and it is annoying to no end. Also make sure you have the fleet set to patrol, that seems to help sometimes. But as far as the "no division and 0 transports" thing, I have no idea. Also I think if you try to plan more than 1 naval invasion at the same time, it seems to bug it up too. I'm not the most exerpeinced with the naval side of this game, so if anyone can help clear things up that would be great.

Even when it's green too sometimes, hover your mouse over the execute green arrow and it should tell you in Red why it won't execute if you everything seems to be set up fine. Sometimes air superiority is a factor I think?

[7509attack]

Yeah, when I hover over the execute arrow there is nothing in red (I've seen it with the red in there and have fixed everything). Seems that divisions are assigned as I'm not getting the "no division and no transports" message. Thanks for the input though Ned.

[NED STARK]

Yes I know what you mean. I've had that issue as well. Try setting your navy to patrol, vs say search and destroy.

I have found that if you have other divisions assinged to the army performing the naval invasion, that are not assined to the invasion, it will not send the invasion until they have stopped moving. Something about divisions still not in position. This may be it.

You can only assign a certain # of divisions based on your naval invasion research. In the beginning it's like only 10 divisions. If you try to assign 11 it will say 0 divisions.

Yes I know. But I get the 0 divisions bug just trying to send 1 division sometimes and this is with the 2nd tier landing craft. Also OP stated that he is aware of the limit and was trying with 10 or less divisions.

Did you declare war to the country you want to invade?

I had some issues with naval invasion yesterday too. I had to wait untill the invasion is planed 100% before I could start it. Additionally I had to manually assign the army to this specific battleplan (ctrl + LMB). I recognized the amaountof availlable transports assigned to the battleplan takes some time to build up.
To be safe I also assigned some major ships in "escort convoymode" to the area

On a similar note, do you own /control the starting port ?
The game does not allow attacking from neutral territory.

So if you're Germany, staging a Naval Invasion from Axis Italy, the Invasion can only proceed when you Call Italy to arms.

the tooltip should be much simpler and clearer... it should look like the tech tree with green checkmark and red X for each condition required for the naval invasion

Sorry to necro an old thread but I found this while having a similar problem and might have found the solution.

You say you're playing as Japan. It's a long shot but are you trying to invade Guangxi Clique through Macau? 'Cause I spent a whole evening screaming obscenities at my monitor before I realised that Macau is a Portuguese territory, not Guangxi Clique. They share exactly the same national colour.
