Forts won't work as canals

[bitparity]

I don't know if this was meant to be done on purpose, but I spent all this time taking an isthmus only to find out after I built a fort, it wouldn't let my ships cross.

Does anybody know where in the python code this is, maybe I can mod/correct it myself?

strange, I just built a canal and it worked nicely. two plot land barrier between mediterrean and black sea and I had a city there along with a fort and the transition was no problem. played as roman, ca. 760 ad.

A save would be most welcome

My impression was, that canals with one or two castles are still passable but not more than that.

The forts need to be next to water to work. E.g. if you have 3 forts, with the middle one not touching water, you won't be able to pass through.
