Map modding - adding sea provinces

[Tyddyner]

Hello, let me start explaining the problem.
Anyone know why new seazones can have no valid pathes to the other parts of the sea?
I mean, I made an archipelago and seas around it, added seazones numbers to seazones sections in default.map, but I can't move ships to the archipelago waters. Any solutions?
(Made this in sub-mod for EK, but, I think, this problem is not depended to EK).

You might need to edit adjacencies, in adjacencies.csv file.

Adjacencies are not tied with it. I can't move from old seazones to added by myself seazones. This is the problem
