Hello, here comes a weird bug.

I was hosting the game (every DLC), and my friend didn't had the Tempest DLC.

When the community quest about the Krakken appeared, we (me and my friend) get the pop-up about the quest.
But, after this, the krakken wasn't showing on her screen.
But on mine yes :x

She was just front of the krakken but couldn't see him until he attacked her.
Then he killed her army and disapeared on the map again to her.

I still have the gamefile if you need, but i don't know how to give it to you.

Is it possible the multiplayer game was not synchronized ? If it was not, perhaps the weather was not shown/or different on your screens ? The only reason I could imagine, she didn't see the Kraken would be this weather related one:

Fog

On the map: Fleet vision is blocked by tiles affected by this weather type. Note that fleets can see out of fog tiles, just not into them. This means that a fleet in the fog is effectively invisible. In battle: Units in an affected tile gain a defense bonus against ranged attacks.

The game was synchro, and there was no weather. She was at 1 square of the krakken.

You can upload the zipped game file (and other data) here. If you reply and the text box appears, choose one icon to the right from the camera symbol in the upper symbol line.

So, the Epic Ocean boss was stuck between all of my units, but my friend, Amaeline, couldn't see it (even with shared map, shared vision, ect)

She had the mondial quest that ask her to kill it, like me.

But she couldn't see, and it is probably linked by the fact that she didn't had the Boats DLC.

We finished this game like 5/6 days ago, and she had the dlc, and could see it now.
