Campaign Broken? Unfinishable?

[Campaign Broken? Unfinishable?]

I'm a good bit into the campaign. Two things have me stuck:

1) I can't find the Marshes Upgrade, I've searched all the newer islands on the eastern side of the map. Nothing. I've gone back to a few of the starter islands in the campaign and when I search the islands I don't even get a message after hacking the lab. Is it missing? Broken? Without it I cannot attack the Marsh Islands.

same Problem here: I can't find the marshes Upgrade

[Marshes Upgrade in campaign, where is it?]

I have all islands, except the marshes ones, but I can't do them too, because I didn't found the marshes upgrade.

Dunno how to find the marshes upgrade
