Found you uploaded this at 2 hours old. Mod/scenario doesn't run. See picture.

Will also add that the Oceanus (1) scenario gives you options to choose your difficulty. This isn't appearing now.

This is a complete remake of the old Oceanus now you choose to play the mod by setting the game mode from default to Oceanus and forget the old difficult settings
BTW now we have bitters on water if you don't like them disable aquatic bitters in the mod settings

I'm sorry, I do not understand your message. I don't have options to play your mod scenario when Oceanus 2 is installed. I have no problems loading or installing the mod, but the mod scenario is not working for me. I can't choose it on new game, and the screenshot is all I have to help you at this time.

uninstall the old oceanus cause it's not needed anymore and when you init a new game on top of the window you'll see a dropbox written default change it to oceanus and forget about different difficulties in scenario

That helps! Got it now. I would recommend a screenshot on the mod page on that dropdown/setting - since it's different from Oceanus (1) startup. I appreciate the feedback! [close/fixed]

I have not gotten 1 crashed in scenario for a streak of 14hrs 21min in multiplayer. I believe the reason of the crashes are other mods inflicting with this one. Do you know what mods are doing it?

Sorry without more information it is really hard to tell
I'm playing oceanus 2 right now with dozens of other mods without problems
