"This is not a valid province for Invasion" - Why?

[CelsiuZ]

What does this even mean?! I cannot invade anywhere in the paciffic due to this ridicolous message.

I have 10 Marines, with support companies, 169 available convoys, Air and Sea superiority, and all 3 levels of Naval Invasion Research done.

WHAT does this mean, how do I fix it? It makes no sense.

[Inquisitioner]

I believe it needs to be an enemy dock or adjacent to it. There's also the "we know too little about this area" red bars that means you don't have a dock close enough to reach it. Finally you can only have one sea invasion plan at the time and only invade enemies.

It's a true pain in the ass to do naval invasions...

[CelsiuZ]

No! You can invade anywhere, there doesn't have to be a naval dock where you invade. Only from where you are launching it.

I know everything about the island, Radar coverage, ships and air superiority.


What I ended up figuirng out is that the game doesnt care about my landincraft research, I can only land with 8 troops per country. That's it. Sometimes even less.

Paratroops and Marines are not fun to deal with. They are far too finickey.

I hate the marines the most because you need to assign ships to keep naval superiority which is fine... BUT you can only have like 6 zones covered before the game tells you that you can't give any more naval missions. So that really sucked when I was invading Japan from the US main land. The only reason it worked was me abandoning superiority the moment the first invasion was launched (the game won't cancel it) and then moving on to the next invasion army, etc.

[CelsiuZ]

I cant invade Japan (currently playing US). The game keeps telling me I have 8 units slected in a naval invasion, when only 3 are assigned.

Hoi is so ♥♥♥♥♥♥♥ broken I swear. Ugh, the issues of my love hate relationship for this game.

[Karmine]

Well do you somewhere have Naval Invasion order where 8 units are assigned to that you forgot about ? Because if you only have first Naval Invasion Researched it is max 10 Units total, not for each naval invasion it is for all naval invasions combined. If left old Naval Invasion commands open with still units on them (they don't disappear simply from finishing their invasion.

[pmpdadypenguinmn]

is it too far away. there is a distance limit to how far you can launch an invasion

[Quagmire]

Something you're not doing right, I have never had issues with invading by land, sea or air.

[CelsiuZ]

Its not too far away, I'm literally Island hopping. If they were fit swimmers they'd swim across.

So, lets make a list of things I do, so I dont get the same replies everyone gets when they complain about the "not valid province".

Prereq: Have all Marine researches done/have all naval landingcraft research done.

A. I cancel ALL invasion orders ACROSS ALL Armines (no compatibility issues).
B. I put my MARINES in an Army, no more than 8 units per army.
B2. I ensure they have NO ORDERS
C. I move them to the nearest port to my invasion (One army per port)
D. I check to make sure I have and maintain Air/Navy/Radar superiority over enemy islands
E. I now Army by Army create naval invasion plans from 1 port (only 1 army of 8 units in that por) to enemy territory.
E1. Get message "This is not valid terrirotry for naval invasion".
E2. Delete mission, remake it, same result
E3. Delete Army, make smaller army (4 units 1 army)
F. Use this smaller Army, it now works, but the game says 8 units assigned to order in tooltip, but only 4 are shown on the arrow.
G. Rage at the game.

I never have issues with land or air invasions, they work properly. Naval invasions are broken to ♥♥♥♥.

This may be your problem only 1 invasion plan per port, so if you want to launch three simultaneous invasions you require three ports to launch from, everything before that looks correct.

[Yaldabaoth]

I'm pretty sure you are doing it wrong. I never had a problem with naval invasions (except disastrous interface issues).

[pmpdadypenguinmn]

well I had a glitch once that prevented me from doing naval invasions. I turned the game off and on again. Tried that yet? lol

[CelsiuZ]

Yes I've rebooted.

Quagmire, ugh, I will clarify:
I cannot even run 8 units out of 1 port in a naval invasions, I am always limited to 4 or 6.

If I do multiple naval invasions, read C. again, I never station more than ONE army PER PORT. Meaning that I naturally run them from multiple ports.

[Quagmire]

Alright, misunderstood on my part.
Unfortunately I can't offer any other help as I have had no problems running 10 per port, or in later game I run up to 24 per port.

[pmpdadypenguinmn]

how big are the marine divisions? what's their combat width? If they're 50 combat width divisions that could be the problem.

[CelsiuZ]

Oh the Width matters?
They're all sitting at 20.
